Opis:
Purpose: The aim of this paper is to present a modern manufacturing method of production and compare the thermal, mechanical, properties of composite materials with aluminium alloy matrix reinforced by Al2O3 particles. Design/methodology/approach: The material for investigation was manufactured by the method of powder metallurgy (consolidation, pressing, hot concurrent extrusion of powder mixtures of aluminium EN AW-AlCu4Mg1 (A) and ceramic particles Al2O3). The amount of the added powder was in the range of 5 mass.%, 10 mass.% and 15 mass.%. Findings: The received results concerning the enhancement of hardness, which show the possibility of obtaining the MMC composite materials with required microstructure, influencing the properties of the new elaborated composite materials components. Concerning the thermal properties, especially the linear thermal expansion coefficient was measured, as well as the dilatometric change of the sample length was analysed. Practical implications: Concerning practical implications it can be stated that the tested composite materials can be applied among others in the transportation industry, but it requires additional research. Originality/value: The received results show the possibility of obtaining new composite materials with controlled and required microstructure with possible practical implications.

Opis:
This elaboration shows the effect of combined heat treatment and cold working on the structure and utility properties of alloyed copper. As the test material, alloyed copper CuTi4 was employed. The samples were subjected to treatment according to the following schema: 1st variant - supersaturation and ageing, 2nd variant - supersaturation, cold rolling and ageing. The paper presents the results of inicrostructure, hardness, and abrasion resistance. The analysis of the wipe profile geometry was realized using a Zeiss LSM 5 Exciter confocal microscope. Cold working of the supersaturated solid solution affects significantly its hardness but the cold plastic deformation causes deterioration of the wear resistance of the finally aged CuTi4 alloy.

Opis:
An huge interest is observed in last years in metal matrix composite, mostly light metal based, which have found their applications in many industry branches, among others in the aircraft industry, automotive-, and armaments ones, as well as in electrical engineering and electronics, where one of the most important issue is related to the corrosion resistance, especially on the surface layer of the used aluminium alloys. This elaboration presents the influence of ceramic phase on the corrosion resistance, quality of the surface layer its thickness and structure of an anodic layer formed on aluminium alloys. As test materials it was applied the aluminium alloys Al-Si-Cu and Al-Cu-Mg, for which heat treatment processes and corrosion tests were carried out. It was presented herein grindability test results and metallographic examination, as well. Hardness of the treated alloys with those ones subjected to corrosion process were compared.

Opis:
This paper presents the influence of casting method and anodic treatment parameters on thickness and structure of an anodic layer formed on aluminium alloys. As test materials was used the aluminium alloy AlSi9Cu3, which was adopted to the casting process and anodic treatment. In this paper are presented the wear test results and metallographic examination, aswell as hardness of non-anodised and anodised alloys subjected to anodising process.The investigations were performed using light and electron microscopy (AFM) for the microstructure determination. The morphology and size of the layer was also possible to determine. The anodising conditions for surface hardening and itsinfluence on properties was analysed. The structure of the surface laser tray changes in a way, that there is a different thicknessof the produced layer. The aluminium samples were examined in terms of metallography using the optical microscope withdifferent image techniques as well as light microscope. Improving the anodization technology with appliance of differentanodising conditions. Some other investigation should be performed in the future, but the knowledge found in this researchconcerning the proper process parameters for each type of alloy shows an interesting investigation direction. The combinationof metallographic investigation for cast aluminium alloys - including electron microscope investigation - and anodisingparameters makes the investigation very attractive for automobile industry, aviation industry, and others, where aluminium alloys plays an important role.
