Deformation and Fracture Resistance of Steel with a Structure of a Natural Ferrite-Martensite Composite Under High-Speed Impact
Processes of deformation and fracture of a natural ferrite-martensite composite under a local high-speed impact are considered. Targets fabricated from steel 14G2 with an isotropic structure of tempered sorbite and from the composite are studied after impact tests. It is shown that the target from steel 14G2 with sorbite structure is pierced through under the concentrated high-power impact of a bullet. When the target is made of the composite, the bullet ricochets. The mechanisms of the processes occurring in the targets under the impact of a bullet are analyzed.
