Abstract

The relationship between the thermal-physical parameters of TiB2/A356 aluminum matrix composite and the volume fraction of TiB2 was investigated.Based on the secondary development of ProCAST software

the relationship between temperature change and thermal-physical parameters of TiB2/A356Al aluminum matrix composite with varied volumetric fraction of TiB2 was presented.A investment casting aeronautical part was simulated and produced.The results reveal that through increasing the pouring temperature and velocity of alloy melt as well as adding insulation materials around the shell mold

shrinkage porosity and shrinkage hole in the surface of the parts can be eliminated effectively.
