Abstract:

The hot hardness of 27 different heats of titanium and titanium alloys was studied. Tests were conducted on a modified Rockwell machine in an argon atmosphere. Results indicate that low alloy heats lose their hardnesses at a fairly high even rate. On the other hand, high alloy heats hold their hardnesses well up to about 1100 deg F, and then the hardness drops off very sharply with increasing temperature. The influence of alloying elements in promoting resistance to softening was evaluated at 900 deg F. Iron was found to be the most effective with the other elements being arranged in order of decreasing effect, as follows: manganese, molybdenum, aluminum, zirconium, and chromium.
