Texture formation in the surface layer of targets from VT6 alloyunder irradiation with intense pulsed electron beams
The texture formed in the surface layer of recrystallized titanium alloy VT6 irradiated with intense pulsed electron beams (IPEB) in a melting mode has been studied. It was ascertained that irradiation in the melting mode leads to the formation of compression texture and fine globular-lamellar structure in 20 mm thickness surface layer with preferred orientation of α -, α′-, and α″ -plates in parallel or nearly parallel to the surface. Structural changes observed in the surface layer are the cause of IPEB-treatment induced improves of fatigue strength of titanium alloy.
