摘要: 设计了WMoTiTiAl系新型密度梯度材料。分别采用NiCu和FeAl烧结剂，对WMo合金和MoTi合金进行了低温热压烧结，讨论了合金中主要组成元素的结合形式。最终通过在1 473 K, 30 MPa, 1h条件下一次烧结，获得整体致密且平行精度较好的梯度材料，材料的密度在3.81～17.15 g/cm³的较大范围内沿厚度方向呈准连续变化。

Abstract:A new kind of material, WMoTiTiAlsystem functionally graded material, was designed. The hot pressing of WMo and MoTi alloys at a low temperature was studied, and the combination form of main elements in the sintered alloys was also discussed. The dense WMoTiTiAl system FGM withgood parallel precision, was finally obtained through onestep sintering at 1 473 K for 1 h under a pressure of 30 MPa, and its density changes quasicontinuously in its thickness direction within a wide range of 3.81～17.15g/cm³.
