Abstract Due to the high specific strength and modulus, as well as excellent anti-fatigue and creep resistance properties in the high temperature, continuous SiC fibers reinforced titanium matrix composite (SiCf/Ti) has attracted extensive attention. In the paper, we overviewed the manufacture techniques in the fabrication processing of SiCf/Ti composites, including the SiC fiber and coating deposition technique, hot isostatic press (HIP) consolidation technique and component manufacturing. Besides, our study and progress carried out in this area in recent years were summarized. We successfully can make a small bath trial for SiC fiber and also prepare SiCf/Ti composite with brilliant property. In addition, the interfacial reaction investigation in different matrix system consists of Ti alloy, Ti-Al, Al alloy have been performed. The experiments showed that the interface of SiCf/Ti composites can be retained intact with the help of protective coating (C coating) under heat treatment at 1100 ℃ /10h. Moreover, SiC fiber precursor wires of titanium alloy, aluminum alloy, and nickel-based super alloy have been explored through physical vapor deposition technique (PVD), respectively. The most important is that we had a successful tempt to fabricate ring-like component with the size of Ф600mm×160mm at 1∶1 ratio and roll shaft with the size of Ф50mm×300mm were fabricated successfully.
