Continuous SiC fiber reinforced titanium alloy matrix composite (SiCf/Ti) is a potential material in aeronautical field for its excellent mechanical properties. In this work, continuous SiC fiber reinforced TC17 alloy composites (SiCf/TC17) were fabricated by spark plasma sintering (SPS) at different sintering temperatures from 800 to 1000 oC with interval of 50 oC. Consolidated samples were investigated by SEM, EDS and Matrix erosion method. The results showed that the densification degree and the thickness of the interfacial reaction layer increased as the sintering temperature elevated. In addition, the interface reaction layer with typical tooth shape microstructure mainly consisted of TiC and TixSiy, which was quite similar to t that of hot isostatic pressing (HIP) sample. Due to the aggravation of interfacial reaction, there were lots of voids around interfacial layer above 1000 oC, and the residual stress was hardly affected by the sintering temperature. The SiCf/Ti composites can be consolidated at a lower temperature using SPS technology compared with the HIP processing, which is beneficial to the control of the interface reaction together with the reducing of the cost.

Immense Potential

Fiber reinforced titanium alloys hold immense potential for applications in the aerospace industry. However, chemical reaction between the fibers and the titanium alloys at fabrication temperatures leads to the formation of brittle reaction products which limits their development. In the present study, coated SiC fibers have been used to evaluate the effects of surface coating on the reaction zone in the SiC/IMI829 system.IMI829 (Ti-5.5A1-3.5Sn-3.0Zr-0.3Mo-1Nb-0.3Si), a near alpha alloy, in the form of PREP powder (-35 mesh), was used a茸 the matrix. CVD grown AVCO SCS-6 SiC fibers were used as discontinuous reinforcements. These fibers of 142μm diameter contained an overlayer with high Si/C ratio on top of an amorphous carbon layer, the thickness of the coating being ∽ 1μm. SCS-6 fibers, broken into ∽ 2mm lengths, were mixed with IMI829 powder (representing < 0.1vol%) and the mixture was consolidated by HIP'ing at 871°C/0. 28GPa/4h.
