Inverse Hardness Distribution in Quenched Steel Specimen of Complex Form

Influence of the shape complexity on quenching results was investigated by using the computer simulation. An algorithm of computer simulation of transient temperature fields is based on finite volume method. The prediction of specimen hardness is based on Jominy test results. Hardness in specimen points was calculated by the conversion of calculated characteristic cooling time for phase transformation t8/5 to hardness. Heat transfer coefficient and heat conductivity coefficient values involved in mathematical model have been calibrated by inversion method.
