Abstract: Combustion reaction welding technique was used for welding TiB₂ and metal(Mo). The results showed that the main products of combustion reaction were TiB₂ and MoB. When the content of Mo in intermediums was over 60 wt%, Mo would be surplus. Temperature strongly affected samples properties. When the sample was welded at 1500 ℃ with 80 wt% Mo in the intermedium, the value of bending strength was the largest. The largest value of shear strength among all the samples was the one welded at 1500 ℃ with 40 wt% Mo in the intermedium.
