Deformation and Fracture

Transformation of the carbide phase in the structure of heat-refined pearlitic and martensitic steels is studied at various temperature and time parameters of aging. The effect of the morphology of the carbides formed in the structure of the steels during aging on the mechanical properties is investigated. A method of heat treatment is suggested for raising the resistance of structural low-alloy steels to brittle fracture.
