Effect of interfaclal damage on residual tensile strength for SCS-6/Ti-15-3 metal matrix composite

摘要

Effect of thermal cycling is discussed on the performance of a metal matrix composite with special emphasis on the interfacial degradation between fiber and matrix. Material used in this study was Ti-15V-3Gr-3Al-3Sn alloy matrix reinforced by SiC fiber (SCS-6/Ti-15-3 MMC) fabricated by HIP method at 880 deg C under 2 holding times. After thermal cycling the residual tensile strength was determined and the fracture surface was examined by a SEM.
