Abstract
WKMoTiY powder were mechanically alloyed (MA) and then consolidated through spark plasma sintering (SPS). Four different concentrations of molybdenum, i.e., (0, 2, 5, 10) wt%, were applied to investigate the behavior of the alloys. The microstructure, Vickers micro-hardness and thermal shock behavior were analyzed. It is found that the molybdenum doping can mechanically alloy with tungsten and occupy tungsten lattice, which results in a correspondingly decrease of Vickers micro-hardness and thermal conductivity at the room temperature. Among the molybdenum doped samples, WK-2wt% MoTiY alloy displays highly enhanced resistance against thermal shock. It is suggested that appropriate molybdenum doping in WKMoTiY alloy is beneficial in consolidating and improving its thermal shock resistance.
