Plastic properties of semi-products made of copper by the methods of severe plastic deformation

摘要

In this article, the results of determination of plasticity of semi-products made of copper by the methods" of severe plastic deformation (SPD) tj.: Equal Chanel Angular Pressing (ECAP) and Hydroextrusion (HE) are presented. The compression tests have been made with different speed (0,1; 0,01 and 0,001 s~ ) and at different temperature (from ambient temperature up to 400 "C). The tests have been made to determine the plasticity and possibility of further forming of final products from materials obtained by the SPD methods, in such a way as to maintain their unique mechanical properties and structure.
