Аннотация

The paper studies the phase composition, microstructure, and mechanisms of plastic deformation and fracture under impact load in a laminate obtained by pressure welding of VT6 titanium alloy sheets. Under impact loading at 20 and -196°C, the material is delaminated into sheet piles with attendant changes in their fracture rate. At fracture surfaces, the initial crystal structure experiences structural phase decomposition which results in dynamic rotations. In fracture and delamination sublayers, the material is fragmented. The effects are more pronounced at Tdef = -196°C.
