| Popis: |
The hardness of EN8 and C25 steels during Jominy-type end-quench test was numerically estimated. The cooling curve near the quenched end of the specimen was used to estimate the heat flux during quenching. Heat transfer in the specimen during quenching was modeled as a 2D axisymmetric heat conduction coupled with austenite decomposition. The relevant equations were solved inversely for the heat flux with cooling data as input. The microstructure distribution within the specimen was computed, and a hardness model was developed based on microstructure distribution. The measured hardness values were compared with the estimated hardness values. The predicted and experimentally determined hardness along the length of the specimen has been shown to be in good agreement within ±3 HRC/HRB. |
