ARC-CAST MOLYBDENUM-BASE ALLOYS (1962-1964),
Abstract
The influence of in-process solution and solution and aging treatments on the properties of several molybdenum-base alloys is described. Alloys of molybdenum with titanium and/or zirconium were processed to bar stock by extrusion and rolling procedures. Extruded bars were prepared for rolling to final size either by heating to the minimum recrystallization temperature or by the application of optimum solution or solution and aging treatments. The latter procedures resulted in significantly higher recrystallization temperatures and tensile strengths than the procedure involving recrystallization prior to rolling. The high elevated temperature strengths obtained for the molybdenum-base alloys studied resulted from a critically dispersed carbide phase. A limited amount of work indicated that a dispersion hardenable molybdenum-beryllium alloy could be worked by extrusion. Room temperature hardnesses approaching 500 DPH were developed by the application of the proper solution and aging treatments to the extruded molybdenum-beryllium alloy. (Author)
