As a result, some ideas about the fabrication are put forward.The EPMA experiment results show that the main element such as W, Mo, Ti, Ni, Cu, Fe element are changed gradually in W-Mo and W-Mo-Ti FGM. In the layer rich in W, the grain are intervained and are mixed mechanismly. The same is to the layer rich in Mo and W-Mo. These grain felt up by some sinter. In Mo-Ti layer rich in Mo, the grains are also mixed mechanismly. Ni, Cu, Fe element assembled at interface. Ni melt by Cu plays an vital role in sinter effect. The microstructure characteristics result show that the compactness of W-Mo and W-Mo-Ti FGM is good.
