Abstract : The relationship between microstructure and mechanical properties, and the recrystallization variables, temperature, amount of deformation, impurity content, and type of molybdenum powder, have been studied for rolled Mo-Co alloys. Temperature and time at temperature were found to be the most important variables. The 1/2 hour recrystallization temperature, as determined metallographically for Mo-0.15 Co alloy worked 50% was 950C. The alloy was completely recrystallized at 1100C. The anneal that gave the most desirable combination of tensile strength and ductility was 1/2 hour at 1000C followed by a slow furnace cool. The alloy was 10% to 30% recrystallized by this anneal. Increasing the cobalt content from .01 to .15 percent did not appear to alter the recrystallization range of temperature. (Author)
