Abstract
In this paper are described briefly the foundations of an on–line information system developed mainly for optimizing heat treatment technologies and steel selection by predicting the progress of transformation during quenching at various points in engineering components of different chemical compositions. The flexible generation of the recently introduced workpiece transformation diagrams and the distribution of the free specific dimensional changes through the cross–section of the components are presented. Finally, the practical adaptability of the computerized system for judging incidental distortions and quenching cracks, and for providing input data for calculations of internal stresses by the finite–element method is discussed.
