| Abstract: | ungsten/iron functionally graded materials(FGM),in which the volume fractions of tungsten are 0%,25%,50%,75% and 100% respectively,were produced by resistance sintering under ultra high pressure.The effects of components and preparation parameters on the microstructure and mechanical properties of W/Fe FGM were analyzed.It is shown that W/Fe FGM,whose relative density reaches more than 98%,can be obtained at a pressure of 9 GPa and an input power of 11 kW for 60s so that the elemental composition distributi... |
