一种W-2Y(2)O(3)复合材料是与攀时公司（奥地利）合作用粉末冶金方法研制的。利用透射电子显微镜和扫描电子背散射衍射分析了复合材料的微观结构。采用纳米压痕试验、拉伸试验和夏比冲击试验对复合材料的力学性能进行了分析。结果表明，复合材料在673 ~ 1273 K温度下表现出延展性拉伸性能，而在773 ~ 1273 K温度下表现出较弱的夏比冲击性能，吸收能值较低。(C) 2013 Elsevier B.V.版权所有
A W-2Y(2)O(3) composite has been developed by powder metallurgy methods in collaboration with the Plansee Company (Austria). The microstructure of the composite was analyzed using transmission electron microscopy and electron backscatter diffraction in scanning electron microscopy. The mechanical properties of the composite were analyzed using nano-indentation experiments, tensile and Charpy impact tests. It was mainly found that the composite exhibits ductile tensile behavior at 673-1273 K but weak Charpy impact properties, characterized by low absorbed energy values, at 773-1273 K.
