Effect of equal-channel angular pressing on the precipitation kinetics in Cu-Cr-Hf alloys

Abstract An analysis of phases precipitation during the supersaturated solid solution (SSSS) decomposition in binary Cu–Cr, Cu-Hf and ternary Cu–Cr–Hf alloys after equal-channel angular pressing (ECAP) was carried out. ECAP affects the ageing kinetics by changing the sequence of phase precipitation, and accelerates the decomposition of SSSS.
