Abstract
Samples o a 7075 aluminium alloy were prepared by ECAP technique. A total of six passes was performed using route BC.
The samples were deformed at temperatures between room temperature and 300 °C at a constant initial strain rate. The maximum stress decreases with increasing testing temperature.
The values of the yield stress, the maximum stress and the elongation to failure depend also on the ECAP processing conditions.
