| Abstract: | TTT diagrams, CCT diagrams and critical points of steels H13, S7, S5 for annealing were measured and investigated by means of Formastor-Digital full-automatic phase transformation dilatometer in order to make their annealing technology reasonable and scientific. The basis is provided for making a new annealing technology scientifically. The new technology improves the quality of annealed materials, saves energy and increases productivity. |
