Abstract

In this study, the evaluation of shear strength for joined SiC ceramics was conducted by using a torsion test. Two specimen types based on F734-95 ASTM Standard and one proposed for miniature test specimen in this study were prepared. The effects of specimen size and geometry were investigated by using finite-element stress method (FEM) analysis. The specimens were joined by the NITE process with mixed powder of Al₂O₃, Y ₂O₃, SiO₂ and SiC as joining adhesive. Joining was carried out at 1800 °C for 1 h, under an applied pressure of 20 MPa by hot pressing. The fracture surfaces after torsion test were observed by using optical microscopy.
