摘要：
The hot-cracking susceptibility of directionally solidified, Ni-based superalloys obtained by different casting technologies, such as high-rate solidification (HRS) and liquid metal cooling (LMC), are compared in this article. Refined microstructures and the improved castability of LMC castings has been found. The improved hot-cracking resistance in castings using the LMC process can be attributed to the decreased length of the uncompensated zone and to the increased grain boundary cohesion in this zone.
