Comparative insights into microstructure and magnetism of Ni-Mn-Sn Heusler alloys manufactured by electron beam and laser beam powder bed fusion

Additive Manufacturing Letters, 2023
Powder bed fusion (PBF) is a promising but challenging method for additive manufacturing of magnetocaloric Ni-Mn-Sn Heusler alloys, due to the material's inherent brittleness. To produce crack-free near-net-shape parts from prealloyed gas atomized 47.2Ni-
