Item Influense of the Shock Wave Treatment on Fatigue Carbon Steel(Print ABC, Netanya, Israel, 2017) Vakulenko, Igor A.; Lisnyak, Alexander G.; Griaznova, Ludmila; Bolotova, Daria M.EN: The process of introducing additional number of dislocations in the heat-hardened steel after shock wave pulse treatment apparently is not accompanied by the development of dislocation annihilation. Furthermore, implementation of the deformation per cycle for the area of high-cycle fatigue is ensured by the participation of more dislocations. Thus, in the process of shock wave pulse treatment, the vast number of introduced dislocations is mobile and able to interact with further cyclic loading or it takes place additional unlock of previously fixed dislocations after hardening and tempering. Overall, on the destruction surface after treatment with shock wave pulses it is found increased number of dislocations that are located in different crystallographic slip systems. They can be seen as evidence of the development of quite complex dislocation reactions that increases the metal limited endurance during cyclic loading.
