摘要/描述

Based on theoretical analyses, the effect of electric current density on stability of solidification interface mor-phology of QAl24 alloy was studied experimentally. The results show that the experimental results agree well with the theoretical analyses, and the following conclusions can be drawn: the increase of electric current density improves the stability of the solidification interface morphology under the condition of no convection of the liquid metal. Otherwise this convection will slow down the trend of solidification interface developing to stability caused by increasing electric current density.
