研究了亚微米TiB 2和TiC颗粒增强自生铝基复合材料的低周疲劳行为。以TiO 2 -Al-B-C体系为原料，采用反应热压法制备了TiO 2 -Al-B-C复合材料。碳的加入导致了TiC颗粒的形成，但牺牲了脆性的Al 3 Ti相。讨论了亚微米颗粒的形成对复合材料拉伸和疲劳性能的影响。
Low cycle fatigue behavior of in-situ aluminum based composite reinforced with submicron TiB 2 and TiC particulates was investigated. This novel composite was prepared from the TiO 2 -Al-B-C system via reactive hot pressing. The incorporation of carbon into such a system induces the formation of TiC particulate at the expense of brittle Al 3 Ti phase. The influence of submicron particulate formation on the tensile and fatigue properties of the composite is discussed.
