Abstract

The microstructure, phase composition of Ti-6Al-4V alloy specimens subjected to ultrasonic impact treatment and scanning electron beam treatment as well as their deformation behavior under uniaxial tension were investigated. After the ultrasonic impact treatment nanocrystalline α-grains in the surface layer was found. Scanning electron beam treatment leads to formation of acicular α′-phase in the primary β-phase grains. Dislocation glide, twinning and shear banding mechanisms were revealed in scanning electron beam treated Ti-6Al-4V titanium alloy specimens under tension. Formation of nanocrystalline α-phase in the surface layer was due to the strong localization of plastic deformation from the beginning of loading.
