Abstract: A Mo—Si—B-based alloy for a heat-resistant alloy that satisfies, more than conventional, physical properties such as proof stress and hardness adapted to an increase in the melting point of 5 a welding object. The Mo—Si—B-based alloy powder is such that the full width at half maximum of (600) of Mo5SiB2 in X-ray diffraction peak data is 0.08 degrees or more and 0.7 degrees or less.

Abstract: A tungsten electrode material contains a tungsten-based material and oxide particles dispersed in the tungsten-based material. The oxide particles are composed of an oxide solid solution in which a Zr oxide and/or an Hf oxide and an oxide of at least one rare earth selected from the group consisting of Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu are dissolved as a solid solution. A content of the rare-earth oxide with respect to a total amount of the Zr oxide and/or the Hf oxide and the rare-earth oxide is not lower than 66 mol % and not higher than 97 mol %, a content of the oxide solid solution is not lower than 0.5 mass % and not higher than 9 mass %, and the remainder is composed substantially of tungsten.
