Abstract
In the presented work the mechanical properties of a powder metallurgi cally prepared Cu-Al2O3 with 5 vol.% of Al2O3 were tested at temperatu res from 20 to 700-degrees-C and strain rate 4, 5.10(-4)s-1. In the te mperature range from 500 to 600-degrees-C a significant peak of plasti city measured by elongation A5 could be seen due to grain boundary sli p and dynamic polygonization.
