RECRYSTALLIZATION VARIABLES OF FLAT ROLLED MOLYBDENUM-COBALT ALLOYS,

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)
