摘要: 設(shè)計(jì)了WMoTiTiAl系新型密度梯度材料。分別采用NiCu和FeAl燒結(jié)劑，對(duì)WMo合金和MoTi合金進(jìn)行了低溫?zé)釅簾Y(jié)，討論了合金中主要組成元素的結(jié)合形式。最終通過(guò)在1 473 K, 30 MPa, 1h條件下一次燒結(jié)，獲得整體致密且平行精度較好的梯度材料，材料的密度在3.81～17.15 g/cm³的較大范圍內(nèi)沿厚度方向呈準(zhǔn)連續(xù)變化。

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.
