Book Description
The effect of plastic deformation on subsequent decomposition in the alloys Al-Si (1.2 percent Si) and Al-Mg-Si (1.4 percent Mg2Si) was studied with an electron microscope. These alloys were chosen because the first is easily quenched and does not age at room temperature and because in the second no decomposition after quenching and natural aging is detected with the electron microscope (although the properties change). These alloys were chosen also because they could be studied by the oxide-film method. This method was used to study the surface of the samples, which was etched before deformation and aging. It is then possible to observe simultaneously, on the electron photographs, precipitation, the block structure, and those alterations (slip lines, bending of blocks, cracks, etc.) in the submicroscopic structure of the alloys which are caused by deformation.

Influence of the Precipitation state on the Thermal Stability of Severely Deformed Aluminum Alloys
Author: Rolf Berghammer
Publisher: Cuvillier Verlag
ISBN: 373694831X
Category : Technology & Engineering
Languages : en
Pages : 130
Book Description
A promising way to increase the strength of aluminum alloys is by grain refinement. Therefore the production of so-called ultra-fine grained (UFG) microstructures by severe plastic deformation (SPD) is a very interesting topic. One of the most common SPD processes is Equal Channel Angular Pressing (ECAP), which was compared to Confined Channel Die Pressing (CCDP) and cold rolling.In the focus of this work lays on the one hand the influence of different precipitation states on the formation of UFG structures and their influence on the mechanical properties and on the other hand it was examined if the thermal stability of these structures can be improved either by supersaturated solid solution(by impurity drag) or by precipitates (by grain boundary pinning).With a better understanding of the ongoing softening mechanisms a good combination of high strength and good ductility can be achievedby alternating SPD and heat treatment.
