Numerical and Experimental Investigation of the Heat Treated Steel Part Microstructure and Hardness

Abstract:

The approach for coupled experimental and numerical estimation of the heat treated steel part microstructure and hardness is presented. The method is based on the investigation of the austenite transformation in a steel during continuous cooling, Jominy hardenability test and numerical modeling of a quenching process. The presented approach is verified by estimation of the 20CrMo5 steel gear shaft microstructure and hardness. The estimated results are in good agreement with the experimental ones.
