Effect of equal channel angular pressing (ECAP) at room temperature and subsequent annealing at temperatures ranging from 450 to 600°C on microstructure, mechanical properties and electric conductivity of an Al-8%Ce alloy was examined It was shown that Al4Ce-type eutectic particles having plate-like shape break under ECAP; distribution of the particles appears to be more homogeneous. ECAP leads to about two-fold increase in yield stress (YS) and ultimate tensile strength (UTS); ductility and electric conductivity decrease significantly. Under following annealing, the spheroidizing and coagulation of Al4Ce-type particles occur extensively resulting in decreased strength and increased electric conductivity and ductility.
