AB  - As-melt-spun Ni<sub>50.2</sub>Mn<sub>28.3</sub>Ga<sub>21.5</sub> ribbons are subjected to milling and subsequentannealing for various times. With progressing milling time, the martensitictransformation is gradually suppressed, magnetic moment deteriorates, whereasthe crystal structure undergoes a body centered tetragonal (bct) into face centeredcubic (fcc) change. High-resolution transmission electron microscopy demonstratesa twin-deformed zone in fcc powder particles, which works to improvecircularity of as-produced powders. Subsequent annealing of as-milled powdersrestores martensitic transformation and magnetism, as well as it reverts the fccinto the original 5M structure. It is hence showcased that due to an allotropictransformation, brittle Heusler alloys are mechanically optimized for 3D printingwithout loss of their functional properties.
