Phase composition and fine structure of granular bainite in low-carbon low-alloy steel

The phase composition and special features of the structure of granular bainite in low-carbon low-alloy steels formed as a result of decomposition of austenite in the intermediate range under the conditions of continuous cooling are studied. The volume fractions of structural and phase components, the periods of crystal lattices of α-and γ-phases, the types of carbides, and defects of the crystal structure of the metal are determined.
