Analyze of Microstructure of Composition Material Al-Si-Fe System

In this work describe new method receipt composition material AL-SI-FE system. For describe the composition material used the method of power metallurgical. As source material are used technically pure Al and Si, as well as steel 1008. Source powder mingled from correlation 59 %Al-9 %Si-32 %Fe. 2 stage compaction with mechanical and thermal activation ensure produce composition material without crack and void. After baking speed cooling allows to suppress turning the phase Al8Fe2Si in phase Al9Fe2Si2. The microstructure sample was study by scanning electronic microscope. On microstructure is seen that sample has a no rifts and voids that will provide high values of the mechanical properties.

Study of Deformation of Aluminium Alloy in Equal Channel Angular Matrix with Quasi-small Channels Intersection Angle

This article is described the various possible schemes of severe plastic deformation, by ECAP process that allows receiving metal with ultrafine-grained structure. The results of computer simulation and TEM investigations of aluminium alloy 6060 were presented. It is shown that the equal-channel angular pressing in the proposed matrix with a quasi-starched channel joint angle 45° provides the formation of a homogeneous subgrain structure with a size about 0.5 µm and has a positive effect on the mechanical properties of the aluminium alloy
