of Technology, Harbin 150001, China)Abstract:Ti-Al complex with a network microstructure was successfully fabricated by pressure infiltration. The fabricated Ti-Al complex was investigated and analyzed by OM, XRD, SEM and EDS. The temperature of pressure infiltration was reduced by using Al-Si eutectic alloy instead of pure Al, which can effectively decrease non-diffusion reaction between liquid Al......
