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.

电子探针实验结果表明W-Mo系、W-Mo-Ti系梯度功能材料中主要元素W、Mo、Ti、Ni、Fe、Cu分布整体上具有梯度变化规律，发现富W区、富Mo区、W-Mo混合区中颗粒交错分布，基本上以机械混合的形式存在，颗粒之间主要靠烧结剂的粘结作用实现致密化；以Mo为主要组分的Mo-Ti混合区，也是以机械混合的形式存在；Cu溶解于Ni形成固溶体更好地起到活化烧结能力，Ni、Cu、Fe在宏观层间界面富集，有利于烧结致密化。

The disordered solid solution Al was obtained for Fe_(25)Al_(65)Ni_(10) mixture powder. The mechanical alloying of Fe_(0.25)Al_(0.75-x)Ni_x(x=0.05,0.175,0.25) mixture powders result in intermetallic compounds. The results of mechanical alloyed_(1-x)Ni_x (x=0.4,0.6) and (FeAl_3)_(1-x)Ni_x(x=0.1,0.3) mixture powders indicate that the ratio of iron and aluminum determines the formation of intermetallic compounds. The FeNi intermetallic compound, cerium oxide and one unidentified phase were obtained by mechanical alloying FeCeNi_3 and Ce_2 mixture powders.

对于合金化过程中的结构演变采用X射线衍射仪、DTA或DSC热分析仪、SEM进行分析，对Al-Fe-Ni和Ce-Fe-Ni两个三元系的机械合金化过程的研究表明：对于Al-Fe-Ni三元系来说，成分为Fe_(25)Al_(65)Ni_(10)的混合粉末经机械合金化后可生成非晶与纳米晶的混合物；球磨成分为Fe_(0.25)Al_(0.75-x)Ni_x(x=0.05，0.175，0.25)混合粉末，可形成Al_3Ni_2，AlFe_3，AlFe_(0.23)Ni_(0.77)，球磨成分为_(1-x)Ni_x(x=0.4，0.6)和(FeAl_3)_(1-x)Ni_x(x=0.1，0.3)混合粉末，Fe与Al比例相同时球磨所形成的金属间化合物也相同。
