Titanium alloys of near-α Ti–6Al–2Sn–4Zr–2Mo (Ti-6242) and intermetallic γ-TiAl (Ti–48Al–2Cr–2Nb) are commonly served as turbine blade materials operating at elevated temperatures. This study investigated the feasibility of using laser powder bed fusion (L-PBF) to fabricate two Ti–6Al–4V-based bimet...
