Prediction of critical cooling rate under rapid heating rate and short holding time for pearlitic rail steel

Journal of Materials Research and Technology
Critical cooling rate (Vc) is typically employed to assess the ability of forming martensite for pearlitic railway steels. Currently, the examination of Vc is normally conducted by dilatometry analysis under a fully austenitizing condition.
