Abstract:
Fe-based and Cu-based shape memory alloys are interesting alternatives to the performant but costly stoichiometric nickel-titanium . Recently, the powder bed fusion additive manufacturing route has been explored for these systems, leading to interesting mechanical performance. However, the literature on sinter-based AM of shape memory alloys. This work explores the use of both elementary and prealloyed powders to print green parts followed by debinding and sintering. Powder-polymer granules are processed by wet mixing, drying and sieving. Then, a solvent is droped on granules beds, which makes the granules to join to each other in layer, allowing to grow a green body. The microstructure and properties of the sintered parts are characterized and compared with those of reference materials.
