The effect of thermomechanical parameters on texture behavior of AZ63 magnesium alloy

Hot compression test was carried out on extruded AZ63 magnesium alloy samples to investigation of the effect of thermomechanical parameters on AZ63 magnesium alloy texture behavior. At first, samples have been machined on two extruded direction (ED) and normal direction (ND). Then, hot compression test performed at 250 °C and strain rates of 0.01 s-1 and 1 s-1 and various strain. Microstructural investigation and texture evolution reveal that tensile twinning leading to basal texture improvement in roll direction (RD=ED) and compressive twinning causes changing texture align transverse direction (TD) at primarily strain during hot compression test. Also, observation of Texture evolution by pole figures indicate that dynamic recrystallization reduces basal texture intensity in ND samples at high strains.
