Abstract

Abstract: Hardenability curves of 20Cr, 20CrMo and 20CrNiMo steels were measured by end quenching experiments, and the effect of alloying elements on the hardenability was analyzed. The hardenability curves of the three steels with different compositions were simulated and calculated by using Abaqus software and Maynier microstructure prediction model. The results show that the hardenability of the 20Cr, 20CrMo and 20CrNiMo gear steels decreases in turn, and the measured values are in good agreement with those calculated by simulation, which indicates that this method can be used to predict the hardenability curve of the gear steel.

Key words: gear steel, end quenching, Abaqus finite element simulation, hardenability curve
