Synthesis and Low Cycle Fatigue Behavior of In‐situ Al‐based Composite Reinforced with Submicron TiB2 and TiC Particulates

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.
