N2 - In this paper the effect of heat treatment on the structure and magnetic properties of Ni36Co37Al27 alloyobtained by laser powder bed fusion from powders synthesized by mechanical alloying and plasmaspheroidization was studied. This alloy is promising to exhibit a magnetically controlled shape memoryeffect at room temperature. It was shown that the base of the alloy was two-phase (β + γ). Sizes of thestructural elements increases with a rise in annealing temperature (Tann), however, the ratio of γ- to β-phasedecreases from Tann = 900 °С to Tann= 1300 °С, which agrees well with the observed monotonic decrease insaturation magnetization. It was also found that Hc of the alloy increases from 74.9 Oe in non-heat-treatedstate to about 120 Oe after the heat treatment, which is due to a decreased content of γ-phase in combination with the precipitation of γ'-phase inclusions. The results obtained can be used in the future tomanipulate the high-coercivity properties of Ni-Co-Al alloys at different stages of additive manufacturing
