A continuous loading push-out test technique was used to measure the interfacial shear strength of SiC fiber reinforcedTi matrix composites. The interfacial shear strength of samples as-fabricated and after heat exposed at 700 and800°C for 50 h was successfully determined. It has been found that the interfacial shear strength of the specimenexposed at 700°C was higher than that of as-prepared and exposed samples at 800°C. The shear strength of theas-prepared samples was about 112.45 MPa, and increased to about 153.77 MPa after heat-treating at 700°C for50 h, but decreased to 133.11 MPa after treating at 800°C for 50 h. Scanning electron microscope (SEM) was usedto investigate the interfacial morphology of the samples. The brittle phase was the main products of interface forsamples exposed at 800°C, and the interface was easily peeled off.
