AZ31镁合金轧制板材各向异性力学性能研究
Investigation on anisotropic mechanical behavior of AZ31 Mg alloy rolling sheet
摘要
Abstract
The anisotropic mechanical properties of wrought AZ31 alloy sheet with different thickness were studied by uniaxial ten⁃sion and compression tests at room temperature along different directions.The influence of the texture on the macroscopic anisotropy of the sheet was discussed based on crystal plasticity theory.Strong anisotropic mechanical properties and Strength Differential effect SD effect were observed for the wrought Mg alloy sheet.It was found that the compressive and tensile yield strength along rolling direction RD were much lower than the one along transverse direction TD and the tensile yield strength was larger than the compressive one along all directions.It is found that the effect of different rolling processes on the mechanical properties was pro⁃nounced and more precisely the yield strength and elongation were effected. The influence of rolling processes on the anisotropic mechanical properties and SD effect in the AZ31 alloy was analyzed based on experimental observations and crystal plasticity theory in the current work.关键词
