    Opis:
    The paper presents the influence of heat treatment on the structure and corrosion resistance of X5CrNi18-10 steel. To determine the structure which has been obtained after heat treatment the methods of light and scanning electron microscopy with EDS microanalysis were used. The electrochemical corrosion properties of the investigated steel were studied in 3.5% NaCl solution using potentiodynamic polarization tests. Basing on the registered curves, the corrosion current, polarization resistance and corrosion potential were determined. The corrosion tests were followed by fractographic researches.

    Opis:
    AISI 304 austenitic stainless steel is recommended and used for various applications in industry, architecture and medicine. Presence of halides in environment evokes a possibility of the local corrosion which limits seriously exploitation of this material in aggressive conditions. The presented paper is focused on the pitting corrosion resistance (“as received” steel surface) in 1M chloride solution (pH=1.2) at a common (20 °C) and an elevated (50 °C) ambient temperatures. 24-hours exposure immersion test (ASTM G48) and cyclic potentiodynamic test (ASTM G61) are used as the independent test methods. The exposure immersion test is carried out with cross-rolled and longitudinally rolled specimens and the effect of direction of rolling on the resistance to pitting is studied.

    Opis:
    Cr-Ni-Mo stainless steels are susceptible to the pitting in aggressive chloride environments. One of the possible ways for the influence of their corrosion behavior is the use of inhibitors as the chemical modification of the environment. The resistance of AISI 316Ti stainless steel to the pitting with/without the inorganic inhibitor was tested by two independent corrosion tests: 24-hours exposure immersion and potentiodynamic polarization test. Both tests were carried out in 1M chloride acidic solution with/without 0.1M molybdate inhibitor at room temperature. Results of immersion tests were evaluated by the corrosion rates calculated from corrosion losses and by the morphology of the pitting. Potentiodynamic polarization curves were evaluated by the pitting potentials.

    Opis:
    Purpose: The present work aims to investigate the influence of CO2 laser spot welding (LSW) parameters on welding profile and mechanical properties of lap joint of AISI 321 thin sheet metals, and analyze the welding profile numerically by finite element (FE) method. Design/methodology/approach: The weld carried out using 150 W CO2 continues wave laser system. The impact of exposure time and laser power on the welding profile was investigated using an optical microscope. Microhardness and tensile strength tests were used to evaluate the mechanical properties of the joint. Ansys software was utilized to simulate the welding profile numerically. Findings: The results revealed that 2 s exposure time and 50 W power have led to uniform welding profile and highest shear force (340 N), lower hardness gradient across the heat affected zone (HAZ) and fusion zone (FZ). Finite element (FE) analysis of the welding profile showed good agreement with experimental analysis. Research limitations/implications: The selection of laser spot welding parameters for thin sheet metal was critical due to the probability of metal vaporisation with extra heat input during welding. Practical implications: Laser welding of AISI 321 steel is used in multiple industrial sectors such as power plants, petroleum refinement stations, pharmaceutical industry, and households. Thus, selecting the best welding parameters ensures high-quality joint. Originality/value: The use of CO2 laser in continuous wave (CW) mode instead of pulse mode for spot welding of thin sheet metal of AISI 321 austenitic stainless steel consider a real challenge because of the difficulty of control the heat input via proper selection of the welding parameters in order to not burn the processed target. Besides, the maintenance is easier and operation cost is lower in continuous CO2 than pulse mode.

    Opis:
    The paper presents the results of microstructural and mechanical investigation of long-term aged TP347HFG austenitic stainless steel. Ageing was performed at a time of up to 30 000 hours and the temperature of 600 and 650◦C. Ageing was proved to lead to the precipitation of secondary phase particles not only inside grains but also on the boundaries of grains and twins. The MX precipitates were observed inside the grains. However, M23C6 carbides and sigma phase precipitates were observed on grain boundaries. The changes in the microstructure of the examined steel translated into the mechanical properties, i.e. initially observed growth and then the decrease of yield strength and a gradual decrease in impact energy. The overageing process – a decrease in strength properties – was associated with the growth of the size of M23C6 carbides and the precipitation of the sigma phase. The reduction of impact energy in TP347HFG austenitic stainless steel was found to be associated with the precipitation of M23C6 carbides in the case of the 600◦C temperature, and the M23C6 carbides and sigma phase in the case of the 650◦C temperature. The rate of changes in the microstructure and mechanical properties depended on the ageing temperature.

    The paper describes the process of stress corrosion in a Ø50 mm rod made of AISI 304L austenitic chromium-nickel steel. Discs cut off from the steel rod were moved at a speed of 1.25 m/s for a test period of 408 h in a corrosive environment of aqueous solution containing 3% HCl and 8.6 g NaCl at room temperature. It was found that deepest cracks and irregular pitting occurred locally in areas of microstructure containing grains of hard lamellar &alpha' martensite and along boundaries between filamentary delta ferrite (Feδ) precipitates and &alpha′ phase. The corrosion developed in a trans-crystalline manner with branches propagating along boundaries of lamellar &alpha′ phase grains.

    Opis:
    The paper presents the results of the basic mechanical properties determined in the static tensile test, impact un-notched Charpy test and hardness of austenitic stainless steel type 316L produced by two techniques: classical pressing and sintering in a vacuum with rapid cooling and selective laser melting (SLM). In this work fracture surface of Charpy test, samples were studied. The results indicate that application of selective laser melting (SLM) makes it possible to double increase the strength properties of components manufactured from austenitic stainless steel type 316L compared to sintering in a vacuum. Resulted in mechanical properties strongly depend on porosity characteristic and the presence of superficial oxides in the case of sintered steel and the character of observed microstructural defects deriving from non-fully melted powder particles and the formation of voids between subsequently melted pool tracks during the SLM.

    Opis:
    Exhaust systems are susceptible to in-service wear because of their exposition to the very aggressive corrosive environment. Various stainless steels grades (mostly ferritic and austenitic, but also martensitic and duplex) and protective coatings are currently used for exhaust system elements to increase their aestetics and corrosion resistance. This article focuses on evaluation and comparison of the common corrosion properties of two stainless steels with different microstructures (ferritic and austenitic) used for exhaust system components at the low ambient temperature (35 °C). An aggressive acidic corrosion solution for electrochemical cyclic potentiodynamic tests (ASTM G61) was chosen to simulate partly inner (condensate) and also external environment (reaction of exhaust gases with water, chlorides in solution after winter road maintenance). Exposure tests of the pitting corrosion resistance were performed according to ASTM G48 standard method.

    The paper presents the effect of plastic strain occurring at room temperature in annealed samples of AISI 304L austenitic chromium-nickel steel on content of strain-induced &alpha′ martensite in its structure. The strain was introduced by longitudinal rolling of the samples with constant strain rate of about 300 mm/s and relative cold work ranging from 5% to 90% It has been demonstrated that the share of &alpha′ martensite in microstructure of the steel determined by means of Feritscope FMP30 depends on the degree of cold work.

    Opis:
    Due to the skin effect of eddy currents, the depth of cracks which can be detected by the traditional eddy current probe is very limited. In order to improve the ability of eddy current probes to inspect deep cracks in metal thick-walled structures, a new eddy current probe using an excitation system with phase shifted fields was proposed. Its feasibility for detecting deep cracks was verified by simulation and experiments. The results showed that the penetration depth of eddy currents in austenitic stainless steel is effectively enhanced by using the new probe.

    Opis:
    In present work, the continuation of general and pitting corrosion analysis of austenitic AISI 316Ti (EN 1.4571) stainless steel in Ringer's solution, is presented. The corrosion was studied by using the ATLAS 98 potentiostat with platinum EPT-101 and calomel reference EK-101P electrodes. The three types of specimens, i.e. as received (without any pretreatment), after abrasive mechanical polishing (MP), and after electrochemical polishing (EP), were used. The best pitting corrosion resistance was recorded for electropolished and passivated (in 20% vol. HNO3 for 30 minutes) surface, i.e. the pitting potential was equal to 761 mVSCE (855.4 ± 58.5 mVSCE), while the worst one was recorded for mechanically ground samples and the pitting corrosion potential was equal to 270 mVSCE (378.8 ± 60.3 mVSCE).

    Opis:
    Nuclear power is associated with great environmental risks. In many cases, the problem of accidents of nuclear power plants is related to the use of materials that do not fully meet the following requirements: high corrosion resistance; high temperature resistance; creep resistance; fracture toughness; stability of structure and properties under irradiation. Therefore, studies aimed at finding materials that can withstand long-term loads at high temperatures, aggressive environment and gradual structural degradation under the influence of radiation are relevant. One of the structural materials, which has high resistance to radiation, is austenitic stainless steel. And one of the ways to increase the radiation resistance of parts made of this steel grade is to grind its microstructure to ultra-fine-grained state. Such structures provide a combination of a high level of strength characteristics with high plasticity, which distinguishes such materials from their coarse-grained counterparts. Also, numerous grain boundaries serve as runoff surfaces for radiation defects, preserving the structure, which causes their increased radiation resistance. From all methods for producing sub-ultra-fine grained materials the most promising is the severe plastic deformation (SPD), which can be implemented in the metal in various ways, including radial-shear rolling. This paper presents the results of studies of the process of radial-shear rolling on the mill SVP-08 and its effect on the microstructure and properties of austenitic stainless steel. During the study, bars with a diameter of 13 mm from AISI-321 steel with a grain size of 300-600 nm were obtained, while the mechanical properties increased more than 2 times compared to the initial values.

    Opis:
    The influence of laser shock processing (LSP) on microstructure of the surface layer of an X5CrNi18-10 austenitic stainless steel was studied. The laser treatment was performed using a Q switched Nd:YAG ReNOVAL laser. It was found that the laser shock processing performed under the conditions of 230 MW/cm2 laser power density and pulse duration of 18 ns produced an ablation and melting of the thin surface layer of the treated material, what indicated that the process of LSP was not purely mechanical but rather thermo-mechanical one. However SEM images of the sample cross sections showed that clusters of slip bands were formed during the treatment in the near surface region. Transmission electron microscopy of the laser-shock treated steel have also revealed a very high density of dislocations and stacking faults. The changes in microstructure came down to 70 µm. It has been found that the laser shock processing induced plastic deformation of the surface layer of the investigated material.
    Celem pracy była ocena wpływu laserowej obróbki odkształcającej na mikrostrukturę warstwy wierzchniej stali austenitycznej X5CrNi18-10. Proces laserowego odkształcania przeprowadzono za pomocą lasera impulsowego ReNOVALaser Nd:YAG z modulacją Q. W wyniku laserowego odkształcania stali impulsem lasera o gęstości mocy 230 MW/cm2 i czasie trwania impulsu 18 ns nastąpiło przetopienie cienkiej warstwy materiału, co wskazuje, że proces LSP nie był czysto mechaniczny, ale cieplno-plastyczny. Badania przeprowadzone za pomocą skaningowego i transmisyjnego mikroskopu elektronowego wykazały, że pod cienką warstwą przetopioną znajduje się materiał odkształcony. Na wytrawionych zgładach poprzecznych stali austenitycznej pod cienką warstwą przetopioną ujawniono obecność licznych pasm poślizgu. W mikrostrukturze warstwy wierzchniej stali austenitycznej po laserowej obróbce występowała duża gęstość dyslokacji oraz liczne błędy ułożenia. Badania wykazały, że zastosowane parametry procesu LSP, powodują odkształcenie plastyczne warstwy wierzchniej badanej stali austenitycznej.

    Opis:
    In this paper the properties of the austenitic stainless steel reinforced with various volume fractions of TiB2 ceramics have been studied. The high pressure- high temperature (HP-HT) method of sintering was applied to the formation of composites. Samples were sintered at pressure of 5 and 7 ±0.2 GPa and temperatures of 1273 K and 1573 K. For the tested materials, the relative density, Young’s modulus and hardness were measured. In order to investigate the structure changes, the scanning electron microscope was used. The obtained results show that the temperature and pressure influence on the mechanical and physical properties of the investigated composites.
    W prezentowanej pracy zbadano właściwości stali austenitycznej z różnym udziałem objętościowym ceramiki TiB2. Do wytworzenia spieków kompozytowych proszków zastosowano spiekanie wysokociśnieniowe HP-HT. Próbki były spiekane przy ciśnieniu 5 oraz 7±0.2 GPa i temperatururze 1273 K oraz 1573 K. Kompozyty poddano badaniom gęstości, modułu Younga oraz twardości. Badania mikrostruktury przeprowadzono za pomocą skaningowej mikroskopii elektronowej. Uzyskane wyniki badań wykazały, że temperatura oraz ciśnienie wpływają na mechaniczne oraz fizyczne wł aściwości materiałów kompozytowych.
