<p>A refractory metal-based alloy material exhibiting high strength and high recrystallization temperature includes a worked material obtained by carburizing, while using a carbon source and coexisted oxygen, a material containing nitride particles of a solute metal dispersed and precipitated in a matrix by multi-step nitriding of a worked alloy material containing one metal selected from Mo, W, and Cr as a matrix and at least one element selected from Ti, Zr, Hf, V, Nb, and Ta as the solute metal, wherein the worked material contains carbon segregated at grain boundaries as a result of the carburizing and oxide particles converted from the nitride particles.</p> |
