Microstructure Stability and Creep Behaviour of a Cu-0.2wt.%Zr Alloy Processed by Equal-Channel Angular Pressing

Original language description

A dispersion-strengthened Cu-0.2 wt.% Zr alloy was subjected to ECAP at room temperature for up to 12 passes through route BC. The microstructural investigations were performed using both TEM and SEM. Tensile creep tests were conducted at temperature 673K and at the applied stress in the range from 80 to 180 MPa. The migration of boundaries and subsequent grain growth were restricted by Cu9Zr2 precipitates. The study was performed in order to evaluate the effects of severe plastic deformation and precipitation on creep behaviour and microstructure of the pressed alloy. It was found that creep behaviour is strongly dependent on number of ECAP passes. The pressed alloy after up to 4 ECAP passes exhibited a considerable improvement in creep properties incomparison with the unpressed alloy.
