AZ31 magnesium alloy is prepared by self-designed equipment.By the analysis of microstructure,XRD pattern and the compressing experiment at room temperature(RT),the effects of the directional solidification technique on crystal orientations and mechanical properties at RT of AZ31 magnesium alloy are studied.The experiment reveals that columnar structures form with this technique and the second spherical phase distribute equally in the matrix.During the process,crystals grow regularly in some direction and show an apparent orientation preference due to the effect of temperature gradient.Moreover,the RT mechanical properties and plastic deformation show anisotropy.
