Ms. Gu et al., MODELING THE EVOLUTION OF MICROSTRUCTURE IN THE HEAT-AFFECTED ZONE OFSTEADY-STATE WELDS, Canadian metallurgical quarterly, 32(4), 1993, pp. 351-361
The evolution of microstructure in a weld has been analyzed under stea
dy state conditions. The history dependent parameters are integrated a
long flow lines. A data structure to assist in creating flow lines and
setting starting conditions of the flow lines is described. The metho
d has been applied to two welds and has proved to be fast and efficien
t. A significant gain in computing speed and/or spatial resolution ove
r transient analyses has been achieved.
