Abstract

The moving direction of the grain boundary (GB), after solidification in the weld metal of AISI310S stainless steel, was examined through a computer simulation technique using the vertex dynamics model and by observing the microstructure. The results are as follows. (1) The grain-growth exponent in the vertex model was fitted to describe the experimental data. (2) The vertex dynamics model can predict the moving direction of a grain boundary in the weld metal after solidification.
