Effect of Severe Plastic Deformation on the Microstructure and Mechanical of Bulk AZ31 Magnesium Alloy

摘要：

　　Magnesium alloy as a new type of metal material has been widely used in many fields.However,magnesium has the hcp structure,poor plasticity and hard deformation during forming processing.The grain refinement can help to improve the plastic properties of the metals.Therefore,the grain refinement of magnesium alloys has become a popular research field.In this paper,equal channel angular pressing technology (ECAP) is used to make large plastic deformation of magnesium alloy,ECAP processing and relevant process parameters have been obtained by using finite element method.The strain distributions in the workpieces and the loads of on the dies have been studied.
