The article presents results of tests of the trimetalic joint AA2519-AA1050-Ti6Al4V performed by explosive welding. Shown characteristics of bending of trimetal in a raw state, after annealing at 530⁰C for 120minutes and annealing with additionally aging at 165⁰C for 600minutes. For the obtained specimens were performed bending tests acc. to ASTM E-290-14 and analysis of microhardness changes in the joint. Performed studies shown that the applied heat treatments increases, in varying degrees, strength and microhardness of each layer of trimetal. The largest increase of strength and microhardness was obtained after annealing with additional aging.
