Laser powder bed fusion of a Fe–Mn–Si shape memory alloy

The iron-based Fe–17Mn–5Si–10Cr–4Ni shape memory alloy (SMA) has been manufactured by laser powder bed fusion (LPBF) for the first time. High strength, elongation and ductility are observed after annealing. In addition, pronounced effect (SME) pseudo-elasticity (PE), which exceed those measured conventionally fabricated Fe–17Mn–5Si–10Cr–4Ni-1(V,C) containing VC precipitates, achieved. texture generated during LPBF process brings to SME PE highly dependent on orientation of loading direction with respect build direction. Improved strain recovery is when parallel due an increased amount (101) orientated grains high Schmid factor low yield strength phase transformation. Pronounced also obtained in more complex geometries successfully same manufacturing technique.
