Experimental study of squeeze casting of AZ31 magnesium alloy

摘要：

　　A new high-strength magnesium alloy with better properties than that of AZ31 was developed.The effect of applied pressure during squeeze casting on microstructures and properties of the alloy was studied by means of techniques such as standard mechanical tester,Brinell Hardness Tester (BHT),and Metallographie Microscope (MM).The parameters studied include squeeze casting pressure,melt temperature and pressure holding time by using orthogonal experimental method.It was found that a squeeze casting pressure of 110 MPa and a melt and pressure holding time of 700 ℃ and 15s respectively gave a good combination of mechanical properties in AZ31 Mg alloy.This was primarily due to effective die filling,microstructural refinement and good heat transfer between the molten metal and the mould.
