Abstract: Iron-based shape-memory alloys (Fe-SMAs) have attracted significant attention due to their unique properties and potential applications.Among these alloys, the polycrystalline Fe-Ni-Co-Al-Ta-B (NCATB) alloy stands out as a promising alternative to NiTi-based SMAs owing to its superior superelastic (SE) behaviour.The SE properties of Fe-SMAs are intrinsically linked to the thermoelastic (TE) nature of their martensitic structure.This structure is achieved through a combination of appropriate fabrication processes and thermomechanical treatments (TMTs).These processes facilitate the formation of precipitates and the development of a dominant texture along specific directions and planes.Previous research has demonstrated the remarkable SE capability of the NCATB alloy, achieving a strain value of 13.5% at room temperature.This remarkable achievement was attributed to the cold-rolling fabrication process, which involved an extreme deformation of 98.6%.However, this process resulted in extremely thin sheets (of 0.2 mm thick), posing challenges for practical applications due to the limited size and form factor.To advance the development of NCATB alloys
