Abstract
Diffusion-bonded SiC joints were fabricated using molybdenum or titanium thin foils as active inserts by hot-pressing at 1500 and 1700 °C. It was found that defects in the bonded zone were effectively mitigated by reducing oxygen activity during hot-pressing. Robust Mo foil-bonded SiC appeared to normally fail at bom the joint interface and SiC base in shear test by compression loading of double-notched specimens. Apparent shear strength of ~150 MPa was demonstrated by torsional test for both Mo foil-joined SiC with a layered structure of Mo4.8Si3C0.6 and MO2C phases and Ti foil-jointed SiC with mixed structure of Ti3SiC2 and TiCx phases.
