Synthesis and high temperature mechanical properties of Ti3SiC2/SiC composite
A high density Ti3SiC2/20 vol% SiC composite was hot pressed under a uniaxial pressure of 45 MPa for 30 min in an Ar atmosphere at 1600 C. The grain size of the Ti3SiC2/SiC composite was finer than that of monolithic Ti3SiC2, though the composite was hot pressed at a higher temperature, due to the d...

Summary: | A high density Ti3SiC2/20 vol% SiC composite was hot pressed under a uniaxial pressure of 45 MPa for 30 min in an Ar atmosphere at 1600 C. The grain size of the Ti3SiC2/SiC composite was finer than that of monolithic Ti3SiC2, though the composite was hot pressed at a higher temperature, due to the dispersion of SiC particles in the Ti3SiC2 matrix. Room temperature fracture toughness of the composite and Vickers hardness were measured as 5.4 MPa.m1/2 and 1080 kg/mm2, respectively. A higher flexural strength of the composite compared to that of monolithic Ti3SiC2 was measured both at room temperature and up to 1200 C. At 1000 C, the composite showed a lower oxidation rate than that of monolithic Ti3SiC2. 8 refs. |
