Effects of Grain Size and Texture on Thermal Conductivity of AZ31 during Static Recrystallization

Abstract

In this paper, we report the effect of grain size and texture on the thermal conductivity of AZ31 alloys during static recrystallization. The ND surface of the extruded sheet had higher thermal conductivity than the cast material with random texture. As the recrystallization progresses after extrusion, the thermal conductivity tends to increase. It is considered that this is a composite cause of the growth of the grain, decrease of the grain size and development of strong basal texture.
