Tensile tests for the tensile specimen made of AZ31B maenesium alloy pipe were carried out to clarify the effects of annealing temperature, test temperature and strain rate on the mechanical properties. The main experimental results were summarized as follows: (1) Mechanical properties, such as yield stress, tensile strength and elongation, of the specimens after annealed at 523 K, 623 K and 723 K were not different from those of as-received specimen cut ouf of the pipe. (2) The temperature dependence was confirmed that the yield stress and tensile strength linearly decrease and the elongation monotonously increases with rising the test temperature. (3) After tested at room temperature (293K), it could not be found out the detectable differences between the yield stress, tensile strength and elongation on a strain rate of 1.2×10^<-3>s^<-1> and those on 0.6s^<-1>, but at 573K, the strain rate dependence was found out that the yield stress and tensile strength increase and the elongation also rises with increasing the strain rate.
