Abstract: A mechanism of ignition of compact metal samples during their fracture in oxygen is proposed. Ignition is assumed to be initiated by microfragments of the fractured sample at the moment when a crack passes through the volume of the metal, and the limiting stage of interaction is dissociative chemical adsorption of oxygen molecules on the surface of microfragments, which defines the dependence between the capability of materials to ignite during fracture and the pressure of the oxygen-containing medium.

Keywords: metal sample, fracture microfragments, ignition, oxygen adsorption.
