摘要

The generation mechanism of blowhole defects in TiAl-based alloy exhaust valve during the vacuum suction casting process was analyzed. By comparing the morphology and distribution of void defects in TiAl-based alloy exhaust valve fabricated with different process parameters, the type of void defects was identified as blowhole. The reason for the blowhole formation was determined by calculating the fluid state of the alloy melt during the suction casting process with the aid of numerical simulation. By optimizing the casting parameters in the process, the blowhole can be ultimately eliminated.
