Diffusion welding of alumina and Al-Sn alloy

The effect of tin in aluminum on the diffusion weldability of Al2O3 and Al has been investigated. The welding treatment was carried out at 773K and 873K for 1.8ks, 3.6ks and 7.2ks under the pressure of about 2.0MPa in a vacuum of 0.1Pa. The addition of Sn released thermal stress which was introduced...

Summary:The effect of tin in aluminum on the diffusion weldability of Al2O3 and Al has been investigated. The welding treatment was carried out at 773K and 873K for 1.8ks, 3.6ks and 7.2ks under the pressure of about 2.0MPa in a vacuum of 0.1Pa. The addition of Sn released thermal stress which was introduced at and near the welding interface during cooling and resulted in the high shear strength of the welded joint. The addition of both tin and magnesium to aluminum showed the same shear strength as that of Al-Mg alloy, which is higher than that obtained by the single addition of tin.
