摘要
Abstract
The extrusion process of Mg-3Sn alloy rods was simulated by changing extrusion ratio,extrusion temperature and extrusion speed.The extrusion process was optimized,and the extrusion of Mg-3Sn alloy was carried out under the optimized process parameters.The results show that the optimum extrusion ratio,extrusion temperature,and extrusion speed for Mg-3Sn alloy rods are 21,380 ℃ and 3 mm/s,respectively.The grain structure of extrusion bar is refined in the optimization process,and the deformation twin crystal and equiaxed crystal generate in extrusion bars with compact microstructure without holes and extrusion deformation layer defects.The tensile strength and yield strength of extrusion bars greatly improve,and the elongation slightly decreases.The numerical simulation results and the experimental results of extrusion process for Mg-3Sn alloy bars are consistent.关键词
