Optimization of Lost Foam Casting Process of AZ91D Magnesium Alloy Based on Fuzzy Matter-element
摘要
Abstract
Taking the casting temperature,vacuum degree,air pressure and exciting force as the process parameters and the tensile strength,elongation,density and surface hardness as the comprehensive optimization goal,the process parameters of AZ91D magnesium alloy lost foam casting were optimized by using orthogonal test combination with Vague set.The results show that the casting temperature is 720 ℃, the vacuum is -0.03 MPa,the inflation pressure is 0.2 MPa and the exciting force is 1.5 kN.The opti-mized parameters increased the elongation of the casting by 6 .1 7%,the density increased by 6 .5 5%,the surface hardness increased by 6.67% and the tensile strength decreased by only 0.74%.关键词
