The Hot Hardness of Titanium and Titanium Alloys

摘要

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 harnesses at a fairly high even rate. On the other hand, high alloy heats hold their harnesses well up to about 1100°F, and then the hardness drops off very sharply with increasing temperature.
