Abstract

Abstract

To reduce shrinkage cavity defects in Fe-Ni alloy ingots,a numerical simulation model was established by using the finite element software ProCAST. The simulation parameters were verified by anatomical experiment. The effect of molding parameters on porosity distribution in Fe-Ni alloy ingots was investigated and an optimized ingot was obtained. It is found that the parameter setting of heat transfer under vacuum circumstance is relatively reasonable,and the simulation results produce a good fit...
