Effect of the Solid-Solution Treatment on the Die-Casting Structures and Properties of Commercial RE-AZ91D Mg Alloy

Abstract:

Effect of the solid-solution treatment on the structures and properties of the die-casting AZ91D alloy with mixed rare-earth elements was explored.The results show that the the tensile strength and the elongation ratio δ have been improved by solid-solution treatment.The higher the treatment temperature was,the better the improvement were.With the increase of the temperature,the content of β phase was lower when those of M-RE compound and the refinement α phase were higher.The tensile strength can reach 304.74Mpa and the elongation ratio can reach 11% after the solid-solution treatment of 370°C×16h.
