Модификация микроструктуры в процессе ультразвуковой ударной электроискровой обработки сварных швов образцов ВТ6, полученных прокаткой и электронно-лучевой аддитивной технологией

Abstract

This paper presents a comparative analysis of the microstructure and microhardness in the ultrasonic impact electrospark treatment welded joints of wrought and electron beam additive manufactured (EBAM) VT6 titanium alloy. Electron beam welding was carried out by double movement of the electron beam across the wrought and EBAM VT6 samples. The results of metallographic studies have demonstrated that the sizes of the welded joints modification zones of EBAM VT6 samples in the treatment was higher than that of the wrought VT6 samples under the same conditions. The influence of the electrical resistance of the wrought and EBAM VT6 alloy on the microstructure and modification zones sizes of the welded joint has been shown
