The method of modelling of relationships between hardenability and chemical composition of the constructional alloy steels.

Basing on the experimental results of the hardenability investigations, which employed Jominy method, the model of the neutral networks was developed and fully verified experimentally. The model makes it possible to obtain Jominy hardenability curves basing on the steel chemical composition. The model of neural networks, making it possible to design the steel chemical composition, basing on the known Jominy hardenability curve shape, was developed also and fully verified numerically. The practical usability of the models developed is presented.
