Laser beam powder bed fusion of NiTiFe shape memory alloys by in-situ alloying: microstructural evolution and generation of strain glass

In this study, ternary NiTiFe shape memory alloys with different volume energy densities were fabricated by laser beam powder bed fusion technique via mixed pre-alloy NiTi powder and 3 at. % pure Fe powder. The exceptionally low porosity of <0.1% was attained at a volume energy density of 229 J/m...
