Rolling Temperature and Subsequent Annealing on Microstructure, Texture and Mechanical Properties of Consecutive Rolled Mg-2.0Zn-0.8Gd Alloy

摘要：

　　Mg-2.0Zn-0.8Gd (wt.%) alloy was rolled consecutively at different temperatures.The influence of rolling temperature and annealing process on the microstructure,texture and mechanical properties of the sheet were investigated.A deformation microstructure consisting of many intersected twins and a few dynamic recrystallization grains,and a basal texture with basal poles tilting about ? 10-15? from the normal direction towards the rolling direction were observed in the as-rolled sheet after 4 consecutive rolling processes.Static recrystallizaiton took place in the sheet after annealed above 300 ?C.The annealed sheet exhibited a uniform microstructure and a non-basal texture with basal poles tilting about ? 38-43? from the normal direction towards the transverse direction.The annealed sheets exhibited higher ductility about 32% along the rolling direction and 40% along the transverse direction comparing with the as-rolled sheets.The static recrystallization during annealing process was helpful to modify the texture as well as the dynamic recrystallization during rolling in the RE-containing alloys.
