摘要：

Several austenizing treatments carried out on different types of quench-temper and carburizing steels confirm the relationship which exists between austenitic grain size and the treatment time and temperature parameters. A relationship has been established between the three variables, a regression plane linking them being obtained. A mathematical model is proposed which permits the treatment parameter to be calculated theoretically, and making it possible to obtain from only chemical composition and austenizing temperature the data required to obtain the Jominy curve. The experimental results for diverse steels and the resulting structures agree with those obtained theoretically. A calculation programme has been developed in accordance with the model for both manufacture and quality control.
