Compositional requirements for the synthesis of Fe–Mn–C austenite-martensite composites: Beyond local equilibrium considerations in pearlite formation

Journal of Materials Research and Technology
Recently, a new generation of high strength steels was introduced by utilizing a lateral chemical pattern of an austenite stabilizer to create microstructures of austenite γ and martensite α′ after quenching.

EFFECT OF ALLOYING ON TEMPERATURE OF TRANSFORMATION «PEARLITE – AUSTENITE» IN COMPLEX-ALLOYED WHITE CAST IRONS

Nauka ta progres transportu, 2014
Purpose. Pearlite is not accepted in the microstructure of wear resistant steels and cast irons. To prevent the pearlite by means of appropriate selection of mode of quenching requires the knowledge of the temperature of the critical points Ac1 and Ac3 ...
