Abstract

The microstructure and small-scale properties of horizontally and vertically printed Ti-6Al-4V alloy rods produced by the electron beam melting technique are investigated. Multi-scale characterization and nano-indentation techniques were used to assess the effect of build orientation. The α′ martensite transformed into lamellar α/β structures, where the β-phase is nucleated and formed on the α-lath boundaries. Vertical samples exhibited high hardness due to the ultrafine grains.
