In this work, soda lime silicate glass was joined to powder metallurgically prepared Ti-304L joint with a heat treatment in air. Ti interlayer was oxidized fast and TiO2 layer formed at joining interface. For the used sample size and dimensions, joined glass did not fracture but delaminated from failing TiO2 layer. While developed residual stress levels were not very high (up to 150 MPa) for joined glass, the formed TiO2 layer was exposed to very high residual stress levels (up to 550 MPa). Thus, glass layer was debonded from failing TiO2 layer where high residual stress levels observed. Formed TiO2 layer also reacted with joined glass, leading to some gas bubble defects at the joined glass interface. For successful joining, formation of TiO2 layer and its residual stress levels were found to be important.
