Provided is a molybdenum alloy which is inhibited from suffering local swelling or crystal-grain enlargement even when used at a high temperature of 2,000ºC, and which renders prolongation of the life of members possible. The alloy makes it possible to easily produce large members without the necessity of any complicated processing step. Also provided is a process for producing the alloy. The molybdenum alloy is an alloy produced by mixing a molybdenum (Mo) powder serving as a matrix with an additive powder comprising one or more of Nb, Ta, and W, the amount of the additive powder being 20-50 at.% of the molybdenum powder, and consolidating the mixture. |
