Abstract

Abstract

The hot tearing criteria presented up to now have been comprehensively analysed in the paper. Based on the experimental results and the analysis through the mechanical strength theories, the unreasonable aspect of the customary strain theory of hot tearing is revealed. It is pointed out that the hot tearing is a kind of plastic fracture in essential. The hot tearing potential is defined, and the solidification mechanics criterion is put forward consequently.
