ABSTRACT:
The paper presents the method of modelling of the hardenability of the heat-treatable steels, basing on chemical composition. Multi-layer feedforward neural networks with learning rule based on the error backpropagation algorithm were employed for modelling of the hardenability curves. The neural networks worked out were employed for the computer simulation of the effect of particular alloying elements on the steels’ hardenability. As an example of its application possibility the computer simulation was made of the influence of the particular alloying elements on hardenabiity and obtained results are presented. For the analyses the model chemical compositions of the heat-treatable steel and carburizing one were assumed. Hardness at a fixed criterial distances from the specimen end-quench test was assumed as hardenability measure.
