The paper describes the main regularities of plastic deformation in VT22 titanium alloy and the micromechanisms of its fracture in static tension and in tension after different dynamic nonequilibrium loading modes resulting from the application of additional pulse loads. It is found that irrespective of the result of loading, the fracture of alloy VT22 occurs by the pore nucleation and coalescence mechanism. The physico-mechanical phenomena underlying the formation of ductile tearing dimples on fracture surfaces are analyzed and their relation to the deformation processes is described.
