Effect of Spark Plasma Sintering Temperature on the Consolidation of SiC Fiber Reinforced Titanium Alloy Matrix Composites

Abstract:

Continuous SiC fiber reinforced titanium alloy matrix composite (SiC_f/Ti) is a potential material in aeronautical field for its excellent mechanical properties. In this work, continuous SiC fiber reinforced TC17 alloy composites (SiC_f/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 Ti_xSi_y, 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 SiC_f/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.
