Abstract: In this paper,the microstructure of linear friction welded joints of TA19 titanium alloy with bimodal structure was studied. Moreover, the defor-mation behaviors of the equiaxed primary α phase and the lamellar β transformation structure as well as the formation mechanism of the joint were analyzed. The results show that during linear friction welding, the severe and continuous thermoplastic deformation leads to a successive changing process of the bimodal structure, from structure coarsening, deformation, disintegration to a complete fragmentation, and ultimately it turns into the refined grain equiaxed structure. From heat-affected zone of welded joint to welded center, the equiaxed primary α phase undergoes discontinuous plastic deformation, fragmentation and eventually turns into β phase completely, while the lamellar β transformation structure expe-riences deformation, disintegration and ultimately a complete fragmentation.
