高比重钨合金力学性能影响因素分析

首先考虑液相烧结工艺条件及组分对高比重钨合金微结构和各相性质的影响，再从细观力学的角度考虑高体积百分比钨合金微结构及各相性质对复合材料有效力学性质的影响，从而架起工艺条件及组分与钨合金力学性能之间关系的桥梁，为分析高比重钨合金性能从理论上建立一套方法，从材料设计和制备的角度实现对这种材料性能优化提供一种方案。并应用上述模型和方法对用粉末冶金法制备的两种不同钨含量的钨合金材料微结构和力学性能进行分析。

Effect Factor Analyses for Heavy Tungsten Alloys

First,we studied the effect of the sintering conditions and components on tungsten alloys microstructure and property,and then we thought about the effect of microstructure and each phase property on the effective properties of the composite in the view of micromechanics.At last,a bridge between sintering conditions and mechanical properties of the tungsten alloys were put up.With the help of the bridge,we provided a optimized design for the alloy properties from the aspect of material design to manufacture.Also we obtained some quantitative and qualitative explanations to relationship amon the microstructure,component and mechanic properties for two kinds of classic liquid sintering tungsten alloys.
