Texture formation in the surface layer of VT6 alloy targets irradiated by intense pulsed electron beams

The texture formed in the surface layer of a recrystallized VT6 titanium alloy irradiated by highcurrent pulsed electron beams (HEBs) in a melting mode is studied. It was ascertained that irradiation in the melting mode leads to the formation of compression texture and fine globular-lamellar structu...

Summary:The texture formed in the surface layer of a recrystallized VT6 titanium alloy irradiated by highcurrent pulsed electron beams (HEBs) in a melting mode is studied. It was ascertained that irradiation in the melting mode leads to the formation of compression texture and fine globular-lamellar structure in the surface layer with thickness of 20 μm with preferred orientation of α, α′, and α″ lamellae parallel or nearly parallel to the surface. Structural changes observed in the surface layer are the cause of improvement of fatigue strength of titanium alloy induced by HEB treatment.
