AbstractThe formation of austenite during the continuous heating of steels was investigated using neural network analysis with a Bayesian framework. An extensive database consisting of the detailed chemical composition, Ac1and Ac3temperatures, and the heating rate was compiled for this purpose, using data from the published literature. This was assessed using a neural network, with the aim of modelling the austenite start and finish temperatures. The results from the neural network analysis were consistent with what might be expected from phase transformation theory.MST/3373
