The precipitation behavior and the recrystallization evolution of the Mg alloy have been observed in thermos-compression conditions. The compress were carried out at four temperature, namely 240°C -330°C, with a strain rate of 1, 0.1, 0.01 and 0.001s -1 , respectively. Dynamic precipitation and dynamic recrystallization were observed during the deformations. The beta precipitates morphologies were mainly influenced by the strain rate and the temperature. The dynamic precipitation behavior was influenced by the dynamic recrystallization during the deformation. It indicates that the precipitation dispersion can be separated into two different kinds, plate-like and lath-like, which are likely caused by the enhancement of recrystallization evolution. The evolution of the continuous precipitates revealed that the strain rates is positive to activate the precipitation which have pinning effect to the grain growth. [ABSTRACT FROM AUTHOR] |
