Abstract

YK28-800 double-action numerical press was used to study the effects of extrusion temperature and deformation degree on microstructure and mechanical property of 4032 Al alloy. The results show that the primary silicon distributed more uniformly along with the increase of deformation degree at a certain extrusion temperature. The tensile strength of Al alloy after extruded had less variation, but elongation improved with increase of deformation degree at the temperatures above 350 ℃ when deformation degree was arranged from 25%-70%. However, elongation decreased obviously when the deformation degree was higher than 70%. The maximum of elongation with a certain tensile strength was obtained when extrusion temperature was 400 ℃.
