20.500.12556/RUL-185175 Additive manufacturing of NiTi shape memory alloys for elastocaloric applications a review The elastocaloric (eC) effect, which harnesses the latent heat released during stress-induced transformations of superelastic shape memory alloys (SMAs), offers a promising pathway toward solid-state, environmentally friendly refrigeration technologies. However, the advancement of eC devices is constrained by the limited heat transfer surface area between SMAs and heat transfer fluids, as well as the high mechanical work input relative to the extracted latent heat. Among available SMAs, nickel titanium (NiTi) alloys are the most widely commercialized and exhibit strong potential for eC applications, yet their poor machinability and fabrication challenges hinder widespread implementation. Additive manufacturing (AM) provides a solution by enabling layer-by-layer fabrication of NiTi with complex geometries, thereby enhancing surface area and reducing work input through lattice structures. This review summarizes recent progress in AM-fabricated NiTi for eC applications, with an emphasis on components produced by laser powder bed fusion (LPBF) and directed energy deposition (DED) techniques using both wire and powder feedstocks. Finally, future directions and opportunities for integrating AM NiTi into practical eC devices are discussed. additive manufacturing caloric materials elastocaloric shape memory alloys solid state refrigeration NiTi elastocaloric cooling dodajalna proizvodnja kalorični materiali elastokaloričnost materiali z oblikovnim spominom hlajenje v trdnem stanju NiTi elastokalorično hlajenje true false true Angleški jezik Slovenski jezik Članek v reviji 2026-07-27 09:21:03 2026-07-27 09:21:10 2026-07-28 04:03:52 0000-00-00 00:00:00 2026 0 0 42 str. iss. 46, art. e30524 Vol. 36 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 004.925.84:621.57 1616-301X 10.1002/adfm.202530524 286018051 Setiawan_..._Additive....pdf Setiawan_..._Additive....pdf 1 8EDEE917AE856D74787C918B1130F45A 89e802edb0c2fc107cc514ff0bd14d82d079cb2a226072be743e5d85b85969e6 b45cafc5-898b-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=243438 https://advanced.onlinelibrary.wiley.com/doi/10.1002/adfm.202530524 1 7d79ae75-898b-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=243437 Fakulteta za strojništvo 0 0 0
