Abstract

The industrial Titanium VT22 alloy was irradiated using the high-current pulsed electron beam (HCEB). HCEB method is an effective method to test the materials under extreme volumetric thermo-mechanical and irradiation conditions. The intense electron irradiation resulted in evolution of microstructural composition. It was found that formation of the β-phase, whereas nonirradiated material consists α+β-phases. The corresponding temperature field and mechanical displacement fields were calculated using the finite-element thermoelastic model.
