Decarburization of the Carbon Steel C45 During Annealing in Air [PDF]
Materials and Geoenvironment, 2018 Abstract In production it is necessary to achieve conditions that lead to the minimum decarburization of a steel product’s surfaces. In this study, the hypo-eutectoid carbon steel C45 was annealed in air in the temperature range T a = 600–1100 °C. The annealing times were between t a = ½ h and t

Forming of C45 Steel at Critical Temperature
Procedia Engineering, 2011 AbstractAn important measure in steel processing industry is achieving the required mechanical properties and micro structure of the material. A new phenomenon has been discovered recently which allows to refine ferrite grain significantly and to spheroidise carbides over a very short time compared to conventional heat treatment techniques.
