Effet de l’affinement de grains par déformation plastique sévère (SPD) sur les propriétés des métaux

Abstract

The current work consists of the study of the effect of SPD by ECAP on the microstructural mechanical properties of an AlMg5 alloy. To do this, experimental tests using a device intended for carrying out plastic deformation by ECAP according to two types of roads (road A and road Bc) were carried out. Microstructural observations using an optical microscope reveal a finer seed structure. Hardness measurements for each sample were carried out, it was found that the hardness increases with increasing number of passes.
