ABSTRACT:
A method for hot forging coarse grain materials to enhance hot workability and to refine microstructure is described which comprises the steps of imposing minimum initial deformation at low strain rate to effect initial dynamic recrystallization and grain refinement without fracture, and thereafter increasing the deformation rate to recrystallize the material and further refine grain structure. Depending on the deformation required to achieve full recrystallization at a given rate, deformation rate can be increased a number of times to further refine grain structure.
