Abstract
Abstract : Both H-11 and PH15-7Mo were successfully warm drawn through four ccesively smaller draw dies to a thickness of 0.040 ! 0.003 in. The warm drawing process cannot be considered optimized because of a high attrition rate in point preparation. The loss of load carrying capability in the point and shoulder rea is crtical when working with sections of 0.05 in. thick and less. Sections of 0.06 in. and larger are not appreciably affected. A potential solution to this critical problem is the development of a means of raising the strength level in the point and shoulder area only. Intermediate annealing between draw passes appears beneficial in redcing draw loads when working with such thin sections. The amount of deformation around the periphery of the cross section must be relatively equivalent. Designed experiments with straightening of PH15-7Mo disproved a previosly held beief, and concuded chevrons are caused by ubriation failure. Constant speed, constant power input with the induction heater is a stisfactory means of obtaining temperature control within limis liberalized by necesty to ! 50 F. autho)
