Abstract : Results are given about the positive effect of thermo mechanical treatment on the susceptibility of steel to reverse tempering brittleness. As was later explained, individually and apparently somewhat ahead of us, to an analogous conclusion has also arrived V. D. Sadovskiy and co-workers (1, 2). These investigations included basically, data about impact tenacity. Investigations, connected with structural cause of thermomechanical treatment effect, have not been published. An investigation, together with studying the thermomechanical treatment effect on the magnitude of impact tenacity, was made of the microstructure of steel obtained as result of hardening from forging (rolling) heating.
