DEVELOPMENT AND PRODUCTION OF IMPROVED MOLYBDENUM SHEET BY POWDER-METALLURGY TECHNIQUES

Abstract

Experimental results pertaining to the development of powder-metallurgical Mo-O.5Ti-C sheet are given. The effects of sintering conditions, carbon concentration, rolling schedules, inprocess heat treatments, and sheet surface treatments on the physicochemical characteristics of this improved structural material are discussed. When the residual carbon is at least about 0.02%, the 1200 C ultimate tensile strength is greater than 50 ksi. By using a proper inprocess heat treatment, 1200 C ultimate tensile strengths approaching 70 ksi were obtained. Many sheets were successfully bent 105 degrees by a 4T-radius punch at -75C. They were about 50% recrystallized after 1 hr at 1250C. (Author)
