Popis: | 1. High-temperature thermomechanical treatment of steel 50KhGA (rolling at 900 °, 40% reduction, holding for 2 sec after deformation) substantially improves the cyclic strength as compared with the standard heat treatment (the fatigue limit increases by 60% and the low-cyclic fatigue strength under a stress of 60 kg/mm2 by a factor of 15–60). 2. High fatigue strength is obtained in the case where the material has a fairly high ductility along with high ultimate strength. This combination of properties can be obtained with a developed substructure. |
