Abstract : Rolling and evaluation of the Phase III material has been completed. The effect of various processing parameters on work-ability and final properties is documented. Significant conclusions are: (1) extrusion to rounds or to rectangular cross-section sheet bar can be accomplished equally well, (2) initial rolling of extruded or extruded and forged product can be and is best accomplished in the temperature range of 2300 F, (3) in order to achieve the lowest ductile-brittle transition, final rolling temperatures should not exceed 1550 F, and (4) cross rolling improves both the longitudinal and the transverse bend and tensile properties.
