| Sažetak: | Заглавие с экрана This paper presents the results of the effect of different combinations of heat treatment and nanostructuring of the surface layers on the fatigue life of 09G2S steel. Conducted fatigue tests have shown the effectiveness of the use of ultrasonic mechanical forging surface layers of 09G2S steel. Fatigue life of 09G2S steel with nanostructured surface layer is greater than 80,000 cycles, which is 3.4 times the fatigue life of the quenched samples without nanostructured surface layer, while maintaining the high thermal stability of the nanostructure. Therefore, the formation of the nanostructured surface layer of the structural steel increase cracks initiation stress. |
