Co-authors YAKUSHINA Evgeniya, SEMENOVA Irina, ROSOCHOWSKI Andrzej, GABITOVA Svetlana

This paper presents the microstructure investigation results of linear friction welded joints of Ti-6Al-4V samples with coarse-grained (CG) and ultrafine grained (UFG) structure. The features of phase and structural transformations in the weld and the thermo-mechanically affected areas, as well as the microhardness distribution across the width of the welded joint were demonstrated.
