Preferred orientations ware produced in titanium by cold rolling and cross rolling and in a titanium-aluminum alloy by cold rolling. The reorientations occurring during annealing were studied quantitatively using an x-ray diffractometer. The kinetics of recovery and recrystallization were studied for isothermally annealed 94% cold-rolled titanium. This included grain growth, hardness, line breadth recovery and measure-meats of reorientation on annealing. Activation energies for the several processes were calculated and compared. Titanium was found to behave somewhat different than other metals to annealing. The process of recovery and recrystallization occurs almost simultaneously in cold-rolled titanium.
