“…Figure 3a,b illustrate the specimen size and the implementation method of the tests, respectively. As mentioned above, the bonding interface probably exhibits anisotropic compression-shear properties due to the directional interface morphology [46]. Therefore, as shown in Figure 3c-e, the angles between the shear direction and the direction of detonation wave propagation were set to 90 • , 0 • , and 180 • , respectively.…”

“…The analysis revealed that the differences in the tensile strengths and elongations after fracture of two specimens including TA1/X65 interface was probably related to the directional wave-like bonding interface. When the tensile direction was parallel to the direction of detonation wave propagation, the wave crests on the flyer layer side and the crests on the base layer side mutually meshed [46]; meanwhile, the waves also damaged the continuity of constriction of the tensile specimens.…”

TA1/X65 bimetallic plate has a bright future of application by combining the excellent corrosion resistance of TA1 and the high strength of inexpensive X65 steel, while manufacturing large size TA1/X65 bimetallic plate is still a challenging task. Multi-pass hot-rolling is the most common way to achieve a large size bimetallic plate. In this work, interface characteristic of explosive-welded and multi-pass hot-rolled TA1/X65 bimetallic plate is experimentally studied. The microstructure, composition and microhardness distribution across the TA1/X65 interface are investigated by optical metallographic observation, scanning electron microscope (SEM) observation, energy dispersive spectrometer (EDS) analysis, and Vickers hardness test. Shear tests and stratified tensile tests are conducted with emphasis on impacts of the angle between loading direction and detonation wave propagation direction on interface strength. A straight TA1/X65 interface with periodic morphology of residual peninsula could be observed on the cross section parallel to detonation wave propagation direction, while in most cases there is no residual peninsula morphology on the straight TA1/X65 interface when the cross section is perpendicular to detonation wave propagation direction. TA1/X65 interface of explosive-welded and multi-pass hot-rolled bimetallic plate presents higher bearing capacity for the load perpendicular to detonation wave propagation direction than that for the load parallel to detonation wave propagation direction. The results of this paper have a certain guiding significance for the fabrication of pipes and containers made of explosive-welded and hot-rolled TA1/X65 bimetallic plate.
