摘要：

A study was made of the effect of temperature, time, and cooling rate. The volume percent martensite was the major structural factor that controls strength and ductility independent of alloy addition. Annealing temperature was important at high quench rates. For a given set of annealing conditions the molybdenum alloy generally had the highest tensile strength and lowest total elongation. The increase in yield strength at the lowest volume fraciton studies is related to a jog or discontinuity in the stress-strain curve during tensile testing. This jog was the result of the lack of a sufficient amount of free dislocations.
