Abstract

The austenitic grain growth has been studied in a low carbon HSLA steel using a model of simples carbides and nitrides. A quantitative criterion for abnormal grain growth has been established and the optimal conditions of heat treatment have also been found. These optimal conditions are the time and the temperature that provide the minimum homogeneous grain size. This optimisation is important because the grain growth at the beginning of the γ → α determines the development of this, and the final properties of the structure.
