Effects of extrusion ratio on breadth extrusion of Mg alloy

KONG Xiangfeng,QUAN Gaofeng,YANG Chaofan (Liaoning Province Laboratory of Key Materials for Railway,School of Materials Science and Engineering,Dalian Jiaotong University,Dalian 116028,China)  
As for the breadth extrusion for production,and in comparison with the traditional compression,the breadth extrusion can reduce the energy consumption effectively,and has become an important processing technique for a large-size magnesium alloy.In addition to the required shape and size of product,the grains of magnesium alloy in the extrusion process are refined and the refinement is increasing with the increase of the extrusion ratio,which makes the plasticity and strength improve significantly for the extruded magnesium alloy.The effect of different parameters on the structure and properties of AZ31 magnesium alloy was analyzed.The emphasis was placed on analyzing the role of anisotropy in improving microstructure and performance.
