摘要:
 摘要:针对传统的大塑性变形技术制备超细晶材料存在着生产效率低下、制造成本高等问题,在变通道转角挤压(CCAE)工艺和正挤压工艺(FE)基础上,设计出一套正挤压和变通道转角挤压复合挤压模具。以AZ31镁合金为研究对象,采用Deform3D软件对该工艺进行数值模拟。模拟结果表明: FEECAP复合变形工艺后的累积变形量大于分别进行FE和CCAE两种工艺的累积变形量之和,晶粒尺寸由135μm减小到266μm,晶粒细化效果显著。

Abstract:Due to the inefficiency and highcost of traditional large plastic deformation on the preparation of ultrafine crystal material,a new kinds of compound deformation combined forward extrusion and change channel angular extrusion (FECCAE) mold was designed based on the change channal angular extrusion and forward extrusion(FE)Taking the AZ31 magnesium alloy as the research object,the compound deformation was simulated by Deform 3D softwareThe numerical simulation results shows that the accumulated deformation of FECCAE better than the sum of FE and CCAE,and the grain refining significantly,which decreased from 135μm to 266μm
