Abstract |
The influence of acoustic fields (aeroacoustic and aerothermoacoustic treatment – AAT and ATAT) on the mechanical properties, structure of structural steels 40Kh and 05Kh21AG15N8MFL, and dependence of the values of the impact strength of these steels on the testing temperature within the range of 20 – (–196) °C has been studied. It was established that possibility of increasing the impact strength of steels and reducing the cold brittleness threshold, which is determined by the temperature corresponding to the KCU (KCV) values, which are 1/2 of the average KCU (KCV)+20 – (Тхр.) level, by 30 °C for steels of pearlitic and austenitic grades, is achieved via use of ATAT for the steels 45 and 40Kh, and AAT for the steel 05Kh21AG15N8MFL. In this case, tensile strength did not decrease and yield strength displayed a slight increase for austenite steels. As for the steel 40Kh, use of ATAT was characterized by stable tensile strength and rise of yield strength by approximately 100 MPA, accompanied by ductility increase.
The research was carried out under financial support of the Ministry of Science and Higher Education of Russian Federation (Scientific and research work “Study and prediction of metal gradient strength fields and ductile parameters during cold metal forming processesin the conditions of complicated loading”, FZWF-2024-0006). |
