Abstract

The influence of the extrusion temperature and the extrusion velocity on the microstructure, the texture and the residual stresses in the aluminum alloy AlSi25Cu4Mg1 after indirect extrusion is studied using microscopical methods as well as X-rays and high energy synchrotron X-rays. The results of the experiments indicate that the microstructure of AlSi25Cu4Mg1 is very stable with respect to high billet temperatures while the texture of the samples strongly depends on the billet temperature and the speed of the extrusion. The residual stress state in the bulk of the samples essentially is determined by the microstresses between the Al-matrix and the Si-particles while near the surface of the samples friction effects are visible.
