N2 - A good quality feedstock powder is a critical aspect in additive manufacturing (AM) including extrusion-based 3D-printing. Spherical powders are usually used for this purpose, however their production is rather expensive. In this paper more affordable mechanical alloying (MA) followed by heat treatment (HT) was studied to obtain Co37Ni36Al27 powder that is promising to exhibit a magnetically controlled shape memory effect at room temperature. Utilization of smart materials in AM is relatively new research field that opens wide scientific andengineering prospects. This study presents the results on solid-state crystallization of Co37Ni36Al27 MA powder when heating up to 900 ◦C and associated changes in its coercivity, remanence and saturation magnetization. Itwas shown that coercivity could be manipulated within the range of 40 Oe to 207 Oe by using different annealing temperature and time due to controlled structure evolution. This work is among the first to study ferromagnetic Co–Ni–Al alloys as feedstock materials for additive manufacturing. The novel results obtained in this paper can be further used to control and manipulate magnetic properties of Co–Ni–Al alloys at different stages of AM and to achieve a number of various magnetic states desired for specified purposes in machinery, instrumentation androbotics engineering.
