Popis: 1. In the structure of 110G13L steel hardened immediately after solidification there are carbides characterized by the presence of phosphorous and an increased manganese content up to 30%. 2. In tempering of hardened (purely austenitic) 110G13L steel carbide colonies consisting of plates of cementite-tye carbide with an increased manganese content between which is located α-phase depleted of manganese are formed. In formation of these colonies diffusion of manganese by distances on the order of the interplate distances occurs. 3. As-cast 110G13L steel contains carbides of two types: 1) carbides formed as the result of segregation in solidification with solution of them in heat treatment difficult because of the necessity of diffusion of manganese and phosphorous by signifcant distances; 2) carbides formed in cooling of the casting at temperatures below 900°C (primarily at temperatures of 600°C and lower), which are easily soluble in heat treatment.
