| Abstract Scope |
Iron-based shape memory alloys (Fe-SMAs) have recently received significant attention due to the high interest in developing cost-effective SMA as they have remarkable superelasticity and stable superplastic behavior across a wide temperature range. They can serve as a valuable alternative to NiTi SMA. The development of laser powder bed fusion (LPBF) and the accessibility of metal powders significantly accelerated the production of alloys. The viability and impact of manufacturing processing factors on Fe-SMA alloy are not well understood. This study investigates the effect of LPBF processing parameters on Fe-Mn-Al-Ni SMA characteristics and densification behavior such as crack formation, surface roughness, laser-track geometry and morphology, density, dimensional accuracy, hardness, as well as thermal behavior and phase features. Material characterization and in-situ thermal monitoring were used to characterize the powder and bulk samples and study elemental and phase distribution, defects, surface morphology, surface roughness, density, and thermal behavior. |
