Abstract

Abstract

In this paper TA2 plate of 3 mm × 3 m × 7 m and Q235 steel plate of 9 mm × 3.2 m × 7.2 m are used as the clad plate and the base plate, respectively, large-sized TA1-Q235 titanium-steel clad plates were prepared with four different components of explosives and the shear strength and interface bonding microstructure were studied. The results show that the detonation velocity, brisance and power of explosive increases with the growing content of emulsion explosive. The ultrasonic testing (UT) results show the interface bonding rate of titanium-steel clad prepared with No.4 explosive can reach 100%, exhibiting a maximum average shear strength of 278 MPa. For explosive-welded titanium-steel clad plates, the interfacial bonding with derivative thickness related to the power of explosive. High power of explosive leads to thinner interface bonding and the thinnest interface bonding is 1.1 μm. The formation of titanium-steel clad plates is due to mutual diffusion of titanium element and steel element. With the function of high temperature, intermetallic compounds such as β-Ti, TiFe and TiFe2 are easily formed.
