摘要

Through establishing a three-dimensional axisymmetric finite-element model, the temperature distribution of TC4 alloy ingot during VAR (vacuum arc remelting) process was simulated by moving boundary heat transfer method. The solidification structure and shrinkage porosity (hole) formation in the TC4 alloy ingot during VAR process were visualized by the coupled method of cellular automaton (CA) and finite element (FE) method. The simulated results are well in agreement with experimental ones in grain structure, growth direction of columnar crystal, transformation of columnar grain into equiaxed grain as well as shrinkage porosity (hole).
