Study of the Breakage Region of High Ductility Steel 08G2B Charpy Specimen Fracture

The structure, microhardness, and orientation of individual areas of the breakage region of steel 08G2B Charpy specimens with an ultrafine ferrite-bainite-martensite structure are studied. The contribution of plastic deformation energy in the breakage region to the total energy of Charpy specimen fr...

Zusammenfassung:The structure, microhardness, and orientation of individual areas of the breakage region of steel 08G2B Charpy specimens with an ultrafine ferrite-bainite-martensite structure are studied. The contribution of plastic deformation energy in the breakage region to the total energy of Charpy specimen fracture is assessed.
