“…Moreover, it is recognized that superelastic performance is very sensitive to the applied strain level. The highest superelastic recovery strain in a given material is generally obtained for a narrow range of applied strain [14]. Those aspects confirm that nanoindentation equipped with appropriate indenters is a promising method for revealing whether or not the material can exhibit superelastic deformation and recovery.…”

“…Recently, the Ti-Zr-Nb-Sn bulk system has received much attention and appears promising alloy system for biomedical purpose because it offers opportunity to combine large transformation strains, low elastic modulus and high strength by adjusting alloy concentration and optimization of microstructure, and also shows excellent cyto-and hemo-compatibility with enhanced viability and proliferation of living cells. For instance, Ti-(1~5)Zr-(12~17)Nb-(2~6)Sn [7][8][9], Ti-18Zr-(9~16)Nb-(0~4)Sn [10,11], Ti-20Zr-12Nb-2Sn [12], Ti-24Zr-(8~12)Nb-2Sn [13] and Ti-(40~50)Zr-8Nb-2Sn [14] (at.%) bulk alloys have been reported in literature and some of which have reached superelastic recovery strain up to 7.5% at room temperature.…”

A new Ti-16Zr-13Nb-2Sn superelastic film incorporating β-stabilizing and highly biocompatible elements was elaborated by magnetron sputtering. The morphological, crystallographic and microstructural characteristics of the obtained films were studied by scanning electron microscopy, atomic force microscopy, X-ray diffraction, and transmission electron microscopy. Superelastic response of the film was investigated at local scale by nanoindentation using both spherical and Berkovich indenters. The sputter-deposited film revealed nanograined β microstructure with preferential growth orientation along [110] direction and excellent superelastic recovery at room temperature. Special attention was paid to the indenter geometry influencing reliable evaluation of the superelastic nature of the film. Evolution of the deformation mechanisms during nanoindentation at increasing depths was rationalized by the calculated representative strain beneath the indenting tips and is discussed in this work.

“…have good biocompatibility and are safe as implant materials. Thus, many researchers have been developing implant Ti alloys just containing the aforementioned biocompatibility elements, such as the Ti-Zr series, [88] Ti-Nb series, [89][90][91] Ti-Zr-Nb series, [92] Ti-Nb-Ta-Zr series, [93][94][95] Ti-Zr-Nb-Sn series, [96][97][98] and so on.

“…It was proven earlier that Ti-41Zr-10Nb alloy, despite its high transformation strain, suffers from the stable martensite at RT, which leads to a considerable residual strain [26]. One approach to solve this problem is to introduce additional alloying elements, such as Sn, ensuring desired phase composition and, hence, high functional properties [27][28][29]. Another approach is to tune chemical composition within the ternary Ti-Zr-Nb system.…”

Four novel superelastic alloys, Ti-41Zr-12Nb, Ti-42Zr-11Nb, Ti-43Zr-10Nb, Ti-44Zr-10Nb (at.%), were obtained and studied in terms of their microstructure and mechanical properties. The obtained alloys were subjected to thermomechanical treatment, providing alloys with a pronounced superelastic behavior. Materials phase composition and microstructure were studied using XRD and SEM methods. Based on the XRD results, maximum lattice strains in the [011]β direction were calculated as 5.9%, 6.3%, 7.5%, and 7.2% for Ti-41Zr-12Nb, Ti-42Zr-11Nb, Ti-43Zr-10Nb, and Ti-44Zr-10Nb alloys, respectively. Mechanical properties of the thermomechanically-treated alloys were studied by Vickers microhardness testing, static tensile testing, and superelastic mechanical cycling. The maximum superelastic recovery strains attained at room temperature was 3.7%, 1.9%, 3.2%, and 3.0% for the Ti-41Zr-12Nb, Ti-42Zr-11Nb, Ti-43Zr-10Nb, and Ti-44Zr-10Nb alloys, respectively. Ti-41Zr-12Nb alloy demonstrated the highest ductility, with relative elongation to failure of over 20%, combined with the total recovery strain of more than 6%. Obtained results indicate that Ti-41Zr-12Nb is one the most promising alloys of the Ti-Zr-Nb system, with quite perfect superelastic behavior at room temperature.
