Ti-Ni shape memory alloys have been successfully used in healthcare and biomedical devices such as eyeglass frames, orthodontic arch wires, guide wires and self-expanding stents, owing to their outstanding shape memory and superelastic properties. Ti-Ni shape memory alloys have also been considered attractive materials for biomedical implants. However, there have been long-standing concerns regarding the risk of Ni allergy and hypersensitivity for long term use due to the high amount of Ni content in Ti-Ni shape memory alloys. Over the last decade, b-type Ti-base alloys have been extensively studied as promising candidates for Ni-free biomedical shape memory and superelastic alloys. There has been impressive progress made in understanding the basic characteristics of the martensitic transformation and shape memory behavior of the b-type Ti alloys and this has led to many shape memory alloys being developed. Ni-free Ti-based Shape Memory Alloys reviews the fundamental issues of biomedical b-type Ti base shape memory and superelastic alloys, including martensitic transformation, shape memory and superelastic properties, alloy development, thermomechanical treatment and microstructure control, and biocompatibility. Some unique properties, such as large nonlinear elastic behavior and low Young's modulus, observed in metastable Ti alloys are discussed on the basis of phase stability. It is expected that superelastic Ti alloys will further expand the applications of shape memory alloys within the biomedical field.
