The microfracture mechanism of explosion cladding TA2/A3 interface seems that the microcracks initiate inside the swirls or inside the molten material as well as at the boundary between the molten material and the A3 matrix,and penetrate into the nearby A3 matrix in the direction normal to the tensile load direction under the action of the crack-tip stress field. At the same time, the microcracks initiate along the TA2 /A3 interface, and link up under the tensile load. Terminal cleavage fracture takes place mainly in the recrystallized and grain abnormal growth region on the A3 side in the vicinity of TA2/A3 interface.Localized fracture takes place along the interface molten layer.Correspondent: YANG Yang.(Departnient of Materials.
