The effects of isothermal hold time on the impact property of P/M tungsten-based heavy alloys
碩士 === 遠東技術學院 === 機械研究所 === 93 === Abstract Two tungsten-based heavy alloys of W-3.99Ni-1.71Fe and W-9.79-Mo-4.35Ni-1.81 Fe (wt%) in composition were investigated based on our previous research results. These two powder mixtures were subjected to sintering at 1520℃ for different thermal hold times,...
