摘要：
The effect of Ti and Ta content on solidification behavior and castability of IN792 was studied. Good castability was achieved by proper control of the Ti/Ta ratio. The results indicate that Ti/Ta ratio may affect the final solidification of the remaining interdendritic liquid, and therefore influence the castability. (C) 2002 Acta Materialia Inc.
