Production method and a transition metal carbide containing tungsten alloy of transition metal carbide containing tungsten alloy

摘要

alloy, in particular, it introduced a recrystallized microstructure of tungsten material, the recrystallization By significantly strengthen the weak grain boundaries in the microstructure, low temperature embrittlement, recrystallization embrittlement, irradiation embrittlement is to develop significantly improved alloy material. Group IVA, VA or Group VIA Group step of mechanical alloying of at least one and a metal material selected from carbides of the transition metals, sintering the raw material powder obtained in the step of the mechanical alloying by hot isostatic pressing to process, the sintered to 2000 500 or more obtained alloy obtained in step below, in 10-5s-1 or more 10-2s-1 or less of strain rate, the alloy in the process of applying the plastic deformation of 60% or more By manufacturing, low temperature brittleness, recrystallization embrittlement, irradiation embrittlement alloy material is obtained which is greatly improved.
