摘要: 利用有限元方法探究了颗粒体积分数、颗粒的应变硬化指数、颗粒的间距以及网状结构对新型非晶合金复合材料即金属玻璃基复合材料(Metallic Glass Composites,MGCs)强度和韧性的影响。结果表明:随着颗粒应变硬化指数的增大,复合材料的强度和韧性都有很大提高,颗粒体积分数的增大、颗粒间距的变小和网状结构排布也将提高复合材料的韧性。这些都有利于设计出有较好韧性的复合材料。

Abstract: Finite element method was used to explore particles volume fraction, particles strain hardening index, particles spacing and reticular structure influence on the strength and the ductility of the new amorphous alloy composite materials which was metallic glass composites (MGCs). The results show that with the increase of particles strain hardening index, strength and toughness of the composite material have greatly improved, increase of particles volume fraction, smaller particle spacing and mesh structure configuration will also make the toughness of the composite materials increased. All these will be contributed to designing good toughness of composites.-
