【Abstract】 The joint strength of titanium and stainless steel by explosive welding and the effect on property of interface under different annealing temperature are investigated in this paper. By analysis of metallography and fractography and microhardness, it is shown that interface strength between titanium and stainless steel explosive welded is higher than Ti; different annealing temperatures produce different influences on the welded joint strength. When annealing temperature is below 400℃, the welded joint notch strength does not drop and its value is over 530 MPa, while the annealing temperature is at 500℃,the welded joint notch strength decreases remarkably and its value is lower 420 MPa.更多还原
