The extruded bar of magnesium alloy has growth of crystallographic texture and plastic anisotropy. The more precise mechanical properties of magnesium alloy at the different temperatures are needed to achieve higher-accuracy FE analysis for advanced forming. In this paper, the influence of plastic anisotropy on compressive stress-strain curve and metal flow of AZ31B magnesium alloy was estimated by using the small-cube compression test at the temperatures of 20, 150, 250, and 400℃ in r-, θ-, and z- directions. In the small-cube compression test, the maximum strain ratios of ε_θ/ε_z= 11 and ε_r/ε_z= 10-11 were measured at 100-200℃.
