WebApr 8, 2024 · As the sintering temperature increased to 1000 and 1200 °C, the interfacial shear strength of SiC f /Mu composites was significantly enhanced to ~ 293 MPa and ~ 553 MPa, respectively. Both are strong enough to impede the matrix crack deflection at the fiber/matrix interface [ 20, 21, 22, 23 ]. WebIn the microscope we see evidence of sintering by the growth of bonds or necks between particles. These bonds grow spontaneously by atomic motion induced by the high sintering temperature. Figure 1 (right) is a scanning electron micrograph of the sinter bond formed between nickel particles heated for 30 minutes to 1000C.
