HEAT-RESISTANT MOLYBDENUM ALLOY

摘要

Provided is a heat-resistant molybdenum alloy which has a strength equivalent or superior to that of a conventional molybdenum alloy and which exhibits ductility over a wide temperature range. This heat-resistant molybdenum alloy comprises the first phase which comprises Mo as the main component and the second phase which contains an Mo-Si-B intermetallic compound particle phase, with the balance being unavoidable impurities. In the heat-resistant molybdenum alloy, the Si content is 0.05 to 0.80 mass% and the B content is 0.04 to 0.60 mass%.
