- Abstract
Results of detailed investigations by the method of transmission electron microscopy are presented, and evaluation was performed in the system of chemical composition→structure→properties of welded joints produced by electron beam welding of experimental high-temperature multicomponent titanium alloys doped by niobium and silicon. It was found that in order to eliminate the gradient by strength and fracture toughness, it is necessary to ensure formation of a homogeneous dispersed platelike structure at uniform distribution of the density of dislocations and phase precipitate particles. Such a structure will ensure a high level of mechanical properties and crack resistance of metal in titanium alloy welded joints. 20 Ref., 2 Tabl., 6 Fig.
