Estimation of heat flux obtained during immersion quenching Imre Felde1, Tamás Réti2, G. E.

In this work inverse methods based on gradient optimization techniques and genetic algorithms used for the esimation of heat flux are evaluated. The comparision study of the techinques applied are based on computational results performed by heat treatment simulations.
