This dissertation investigates Ni-free shape memory alloys (SMAs) with potential applications in the biomedical field. The objective is to address the challenges associated with nickel hypersensitivity in traditional NiTi SMAs by developing and characterizing new nickel-free alternatives. A comprehensive literature review was conducted, followed by experimental formulations where different compositions of titanium-based SMAs were synthesized. The resulting materials underwent various thermal treatments to optimize their shape memory properties including pseudoelasticity and shape memory effects. Experimental techniques such as X-ray diffraction (XRD) and mechanical testing were employed to analyze the structural and functional properties of these alloys. The results demonstrate that the derived Ni-free SMAs exhibit comparable mechanical performance and shape memory capabilities to conventional NiTi SMAs, confirming their feasibility for biomedical use. These findings contribute to the ongoing development of biocompatible materials for medical applications, paving the way for further research into alternative SMA formulations that mitigate the risks associated with nickel exposure.
