Surface modification of 3D-printed Ti-6Al-4V parts by continuous electron beam

Abstract

Continuous scanning electron beam treatment was applied to modify the microstructure and mechanical properties of the Ti-6Al-4V titanium alloy parts fabricated by wire-based additive manufacturing technique. Scanning electron microscopy and electron backscatter diffraction reveal the refined microstructure of the melted surface layer of 3D-printed Ti-6Al-4V parts. It was shown that the formation of 20-30 μm size prior β-grains with fine α- and β-lathes within the melted surface layer drastically increases surface microhardness.
