Fine-grained sintered molybdenum alloys dispersed with 0.8mol% ZrC or TaC particles were prepared by mechanical alloying and spark plasma sintering, and tensile properties of the molybdenum alloys were investigated at 300K and at 1170-1770K. The particle-dispersed alloys exhibited much higher strength than a pure molybdenum which was fully recrystallized. Furthermore, the ZrC particle-dispersed alloy showed a large elongation of 120% at 1770K.These excellent tensile properties of the particle-dispersed alloys are attributed to fine-grained microstructure and uniform dispersion of the fine particles.
