Unalloyed molybdenum and the alloys Mo- 0.50% Ti, Mo0.059% Zr, and Mo- 0.49% Ti-0.057% Zr, were studied from the standpoint of effect of fabrication variables on mechanical properties and structural stubility. Strain hardening was accomplished either by rolling or by forging. Working temperatures were 2200 and 3000 deg F. Molybdenum and the alloys were capable of being strain hardened even at low reductions by rolling or forging at 3000 deg F. For any given set of deformation variables. the highest strength propenties and greatest resistance to recrystallization were consistently demonstrated by the ternary alloy Mo-0.49% Ti0.057% Zr. The role of externally applied stresses in influencing the recrystullization behavior of the materials under investigation was found to be quite complex. At least part of the complexity of the problem as approached here resulted from the large number of fabrication variables that were inherent in the test specimens. Four new experimental alloy compositions are discussed. (auth)
