Powder recycling for electron beam powder bed fusion of TiAl alloy

Powder recycling for electron beam powder bed fusion of TiAl alloy

This study systematically investigates the impact of powder recycling (up to 70 cycles) on Ti-48Al-2Cr-2Nb (at.%) alloy processed by electron beam powder bed fusion (EB-PBF). Comprehensive characterization (SEM/XRD/EBSD/XPS) reveals three key phenomena of recycling powder: (1) progressive Al depleti...
