摘要：

Hot compression of AZ31 magnesium alloy was carried out at deformation temperatures of 523-723K and strain rates of 0.01-10s(-1). The effects of deformation process on the microstructure and flow stress were investigated. The flow stress curves showed the characteristic of dynamic recrystallization (DRX) with deformation process parameters. Optical microscopy and TEM observations indicated that dynamic recrystallisation and twins' structure were found during hot compression. Deformation mechanism of AZ31 magnesium alloy at elevated temperature was discussed in this paper.
