Microstructure design of Co-Ni-Ga shape memory alloys by additive manufacturing can be used to prevent intergranular cracking and premature failure. The comparison of microstructure, composition and magnetic properties of Co-Ni-Ga Heusler alloy processed by direct energy deposition and laser powder bed fusion shows large differences in terms of precipitate formation and martensitic transformation behavior.
