晶界形貌、织构对AZ31镁合金各向异性的影响
Effect of the boundary and textures of grains on anisotropy of AZ31 magnesium alloy
摘要
Abstract
The effects of deformation process, grain boundary morphology and textures on the yield strength and elongation anisotropy of AZ31 magnesium alloy were investigated by using metallographic analysis, texture analysis and tensile test. Results show that rolling process can stretch grains and generate straight grain boundaries, when the direction of the tensile stress separated form straight grain boundaries by 45°, AZ31 magnesium alloy all ways has a lower yield strength and high elongation. Analysis indicates that in addition to the textures, the grain boundary morphology also affects the mechanical properties of magnesium alloys; when the direction of tensile stress separated form straight grain boundaries by 0° or 90°, basal slip Schmid factor and tensile twinning were the major factor affecting the mechanical properties of magnesium alloys.关键词
