Abstract:

Shear testing of refractory alloys at elevated temperatures was performed on exothermically brazed joints of unalloyed tungsten, molybdenum, columbium, tantalum, and TZM alloy. Brittle-to ductile transition temperature testing was per formed in order to determine the effects of exo thermic reaction heat on as-received unalloyed tungsten, molybdenum, and TZM alloy. Author
