Opis:
Various examples of the design of cast elements of the equipment used in furnaces for the heat treatment of machine parts are given. Shortcomings in their performance are indicated. Reasons for required stability of equipment are briefly discussed. Elements of equipment illustrate the possibilities of using a charge-carrying pallet with dimensions of 900×600×45 mm as a basis for multi-component technological equipment. Introducing additional elements, such as metal baskets, intermediate pallets or crossbars to the main pallet, it becomes possible to create different configurations of this equipment. The technological equipment presented and discussed here is offered to different plants which heat-treat a wide variety of produced parts. It was found that the reliability and durability of new designed equipment can be checked only during practical use. For large plants dealing with the heat treatment of bulk quantities of parts homogeneous or similar in shape is recommended to use the dedicated tooling.

Opis:
The study presented in this paper concerned the possibility to apply a heat treatment process to ductile cast-iron thin-walled castings in order to remove excessive quantities of pearlite and eutectic cementite precipitates and thus meet the customer’s requirements. After determining the rates of heating a casting up to and cooling down from 900°C feasible in the used production heat treatment furnace (vh = 300°C/h and vc = 200°C/h, respectively), dilatometric tests were carried out to evaluate temperatures Tgr, TAc1start, TAc1end, TAr1start, and TAr1end. The newly acquired knowledge was the base on which conditions for a single-step ferritizing heat treatment securing disintegration of pearlite were developed as well as those of a two-step ferritization process guaranteeing complete disintegration of cementite and arriving at the required ferrite and pearlite content. A purely ferritic matrix and hardness of 119 HB was secured by the treatment scheme: 920°C for 2 hours / vc = 60°C/h / 720°C for 4 hours. A matrix containing 20–45% of pearlite and hardness of 180–182 HB was obtained by applying: 920°C for 2 hours or 4 hours / vc = 200°C/h to 650°C / ambient air.

Opis:
The study presents methods to be used for improving the performance parameters of car engine pistons made of EN AC-AlSi12CuNiMg alloy according to the PN-EN 1706: 2011. Pistons of slow sucking and turbocharged engines were researched. A solution heat and ageing treatments were applied according to four variants. Temperatures of the solution heat treatment were: 550 ±5°C; 510°C ±5°C; and alternate: 276 ±5°C/510 ±5°C. The solution time ranged from 6 min to 4 h. Temperatures of the ageing heat treatment were 20°C and 250°C, while the ageing time ranged from 1,5 to 3h. Natural ageing was performed in 5 days. Measurements of hardness HRB and the piston diameters were performed. An improvement in the performance parameters of combustion engines was observed. Three solution heat treatment and ageing variants, allowed to obtain the pistons with hardness equal/higher than pistons of the turbocharged engines. The test results confirmed the possibility of providing a piston with properties exceeding the high load parameters specified by the manufacturer. Further studies will make it possible to improve the effects of the proposed solutions.

Opis:
Simulation is used today in many contexts, such as simulating technology to tune or optimize performance, safety engineering, testing, training, education, and entertainment. In some industries, simulations are commonly used, but in heat treatment this is rather an exception. The paper compares the simulation of carburization and nitrocementation of 16MnCr5 steel with a practical application. The aim was to determine the applicability of chemical heat treatment simulation. We were looking for an answer to the question: to what extent can we rely on the technological design of heat treatment? The software designed the heat treatment technology. He drew the technological process of chemical-thermal treatment of 16MnCr5 steel. The thickness of the cementite layer was 1 mm and the nitrocementation 1.2 mm. Changes in mechanical properties were observed. Cementing, nitrocementing, hardness, microhardness, metallography, and spectral analysis were practically performed. This article describes the benefits of simulation, speed and accuracy of the process. The only difference was in determining the carbon potential. The simulation confirmed the practical use and its contribution in the technological process.

Opis:
Improvement of properties of silumins in scope of classic methods is connected with changes in morphology of silicon precipitation through: process of modification of alloy, maintaining a suitable temperature of overheating and pouring into moulds, as well as perfection of heat treatment processes. Obtained structure of casting have a direct influence on mechanical and technological properties of machinery parts, and therefore, usage of knowledge on crystallization to control of crystallization’s kinetics of castings in order to optimize obtained structure and introduction of modern methods of heat treatment, enabling considerable improvement of mechanical and technological properties, becomes an important factor. Dispersion hardening with soaking of alloy near temperature of solidus, consisting in heating of poured specimens to temperature of solutioning, keeping in such temperature, cooling down in cold water (20oC), and next operation of artificial ageing have effect on change of tensile strength Rm of a selected hypo-eutectoid silumins. Selection of suitable parameters of dispersion hardening is condition of obtainment of positive results in terms of improvement of tensile strength Rm and has effect on its economic aspects.

Opis:
In this study, Al-0.80Mg-0.85Si alloy was modified with the addition of 0.3 wt.-% zirconium and the variation of microstructural features and mechanical properties were investigated. In order to produce the billets, vertical direct chill casting method was used and billets were homogenized at 580 °C for 6 h. Homogenized billets were subjected to aging practice following three stages: (i) solution annealing at 550 °C for 3 h, (ii) quenching in water, (iii) aging at 180 °C between 0 and 20 h. The hardness measurements were performed for the alloys following the aging process. It was observed that peak hardness value of Al-0.80Mg-0.85Si alloy increased with the addition of zirconium. This finding was very useful to obtain aging parameters for the extruded hollow profiles which are commonly used in automotive industry. Standard tensile tests were applied to aged profiles at room temperature and the results showed that modified alloy had higher mechanical properties compared to the non-modified alloy.

Opis:
Improvement of Al-Si alloys properties in scope of classic method is connected with change of Si precipitations morphology through: using modification of the alloy, maintaining suitable temperature of overheating and pouring process, as well as perfection of heat treatment methods. Growing requirements of the market make it necessary to search after such procedures, which would quickly deliver positive results with simultaneous consideration of economic aspects. Presented in the paper shortened heat treatment with soaking of the alloy at temperature near temperature of solidus could be assumed as the method in the above mentioned understanding of the problem. Such treatment consists in soaking of the alloy to temperature of solutioning, keeping in such temperature, and next, quick quenching in water (20°C) followed by artificial ageing. Temperature ranges of solutioning and ageing treatments implemented in the adopted testing plan were based on analysis of recorded curves from the ATD method. Obtained results relate to dependencies and spatial diagrams describing effect of parameters of the solutioning and ageing treatments on HB hardness of the investigated alloy and change of its microstructure. Performed shortened heat treatment results in precipitation hardening of the investigated 320.0 alloy, what according to expectations produces increased hardness of the material.

Opis:
Cast Hadfield steel is a material with high resistance to abrasion, provided, however, that it is used under the conditions of high dynamic loads. To increase the wear resistance of the alloy under the conditions in which no large pressures are operating, carbide-forming elements are introduced to the alloy. However, this leads to the precipitation in castings, mainly at the grain boundaries, of increased amounts of complex carbides. The heat treatment of cast Hadfield steel consists in solutioning to obtain a purely austenitic structure with no carbide precipitates. Changes in microstructure as a function of the changing temperature of the solution treatment were traced in hammers for crushers cast from high-manganese steel with an addition of chromium (1.7% C, 16% Mn and 1.4% Cr). It has been found that the use of the solution treatment temperatures much higher or prolongation of the solutioning time (compared to standard heat treatment) does not lead to the formation of a purely austenitic structure.

This paper describes the possibility of using very short periods of solution annealing in the heat treatment of unmodified hypoeutectic silumin alloy AlSi7Mg0,3 casted by method of casting with crystallization under pressure with forced convection (direct squeeze casting process). Castings prepared at different casting parameters were subjected to special heat treatment called SST (Silicon Spheroidization Treatment), which were originally used only for the modified silumin alloys to spheroidization of eutectic silicon. Temperature holding time in solution annealing of T6 heat treatment is limited in the SST process to only a few minutes. It was studied the effect of casting parameters and periods of solution annealing on ultimate strength, yield strength, and especially ductility that in the unmodified silumin alloy castings is relatively low.

Opis:
Stopy typu Al-Si-Mg o zawartości krzemu w przedziale 4 do 24 % mas. (siluminy) należą do jednych z najbardziej rozpowszechnionych tworzyw wykorzystywanych w odlewnictwie metali nieżelaznych. Ich wielka popularność spowodowana jest zestawem własności w postaci między innymi niskiej gęstości czy wysokich własności mechanicznych oraz własności odlewniczych. Z drugiej jednak strony charakterystyka procesu technologicznego wykorzystującego tę grupę materiałów sprzyja pojawianiu się w nich porowatości i rzadzizn, które mogą stać się źródłem pęknięć. Metodą umożliwiającą eliminację negatywnych skutków tej grupy defektów jest Powierzchniowa Wysokotemperaturowa Przeróbka Plastyczna (PWPP). Modyfikacja warstwy wierzchniej odlewu za pomocą tego typu obróbki jest szczególnie pożądana w elementach konstrukcyjnych dla przemysłu transportowego, elektromaszynowego czy w budownictwie. Zastosowania te wymagają od odlewów spójnej, pozbawionej nieciągłości struktury warstwy wierzchniej oraz zwiększonych własności mechanicznych. Jednym ze sposobów polepszenia tych drugich jest obróbka cieplna, polegająca na przesycaniu i sztucznym starzeniu. W pracy przedstawiono badania nad doborem optymalnych parametrów obróbki cieplnej w postaci czasu i temperatury starzenia sztucznego dla stopu AlSi7Mg0,3 po procesie PWPP.
Al-Si-Mg cast alloys with a silicon content in the range of 4 to 24 % by weight (silumins) are among the most common materials used in the casting of non-ferrous metals. Their popularity is due to a large set of properties, inter alia, low density or high mechanical properties and casting properties. On the other hand, that uses characteristics of the technological process of this group of materials in the emergence of their porosity and microshrinkage which can be a source of cracks. The method allows the elimination of the negative effects of this group of defects is Surface High-Temperature Plastic Processing (PWPP method). Modification of the surface layer of the cast with this type of treatment is particularly desirable for the structural components of the transport industry, electrical engineering or in the building industry. These applications require a coherent castings, devoid of discontinuity of the surface layer of the structure and increased mechanical properties. One way to improve on the second properties is heat treatment, which consists of oversaturation and artificial aging. The paper presents research on the selection of optimal parameters of heat treatment time and temperature for the AlSi7Mg0,3 alloy after PWPP method.
