中文摘要:
      采用粉末层叠和整体热压烧结的方法,制备了Y2Ti2O7/316L不锈钢功能梯度复合材料。经金相显微镜、X射线衍射仪和电子探针分析确定,该材料在金属和氧化物界面处实现了成分和微观组织的梯度过渡。对不同梯度含量复合材料的力学性能测试表明,界面处的力学性能存在相应的梯度变化,即随各层金属相含量的逐渐增加,过渡区材料的致密度、抗弯强度不断提升,而硬度则不断下降。

英文摘要:
      A Y2Ti2O7/316L stainless steel functionally graded composite material was fabricated through powder lamination and hot-press sintering processing, and its microstructure and some mechanical properties were investigated. The observations of optical microscopy, X-ray diffractometry, and electron probe microanalysis all confirmed the formation of compositional and microstructural gradients in the transition region between the metal and oxide halves. Some mechanical properties of the graded composite were also preliminarily evaluated, by performing the mechanical testing on homogeneous composite samples with different volume fractions of Y2Ti2O7. The results suggested that some mechanical properties vary in the same gradient of composition and microstructure, i.e. relative density and bending strength increase gradually while Vickers hardness decreases gradually with the increase of metal content in the transition region.
