ABSTRACT:
A heat treating method for promoting directional recrystallization in objects in general and, more particularly, forgings having relatively low length to thickness ratios. The objects are partially embedded in containers having insulating material therein. The containers are placed into furnaces wherein the rate of the advancing isotherm travelling through the objects are controlled. This process may be used in lieu of zone annealing and static recrystallization heat treatments.
