半连续等通道挤压过程的力学分析与模拟
Mechanical analysis and simulation of semicontinuous equal-channel angular extrusion process
摘要
Abstract
Based on the idea of equal channel angular extrusion,a new severe plastic deformation( SPD)method called semicontinuous equal channel angular extrusion( SC-ECAE)was proposed and applied to refine the grain of steel. The method can change the driving force from the workpieces to the dies . The process breaks the traditional idea of severe plastic deformation . So that the size of workpiece can be highly improved and the difficulties of SPD equipment can be reduced. It not only can achieve uniform refined grain,but also can offer an exciting prospect for production of ultra-fine grained steel at a commercial scale. Through an analysis of slip line field and finite element simulations,and with the measured data from the prototype machine,the force conditions of the workpieces during SC-ECAE process are also discussed.关键词
