“…[22][23][24][25] On the basis of their chemical compositions and phase constituents, Ti alloys can be generally classified into α-type Ti alloys, near α-type Ti alloys, (α þ β)-type Ti alloys, near β-type Ti alloys, β-type Ti alloys, and Ti-based shape-memory alloys. [12,20,[26][27][28][29][30] α-type and near α-type Ti alloys, which mainly contain α-stabilizers (e.g., Al, O, N, C), have admired weldability, castability, and structure stability but limited low-temperature strength and plasticity. [20,27,31] In comparison, (α þ β)-Ti alloys, containing a certain quantity of β-stabilizers (e.g., V, Mo, Ta, Nb), display a dual-phase microstructure (5-30 vol% β phase) at the room temperature.…”

“…β-type and near β-type Ti alloys contain higher amount of β-stabilizers, hence they are mainly composed of β phase.

Thanks to a considerable number of fascinating properties, titanium (Ti) and Ti alloys play important roles in a variety of industrial sectors. However, Ti and Ti alloys could not satisfy all industrial requirements; the degradation of Ti and Ti alloys always commences on their surfaces in service, which declines the performances of Ti workpieces. Therefore, with aim to further improve their mechanical, corrosion and biological properties, surface modification is often required for Ti and Ti alloys. This article reviews the technologies and recent developments of surface-modification methods with respect to Ti and Ti alloys, including mechanical, physical, chemical, and biochemical technologies. Conventional methods have limited improvement in the properties and/or restriction on the geometry of workpieces. Therefore, many advanced surfacemodification technologies have emerged in recent decades. New methods make Ti and Ti alloys have better performance and extended applications. With requirement of high surface properties in future. Understanding the mechanism in various surface-modification methods, combining the advantages of current technologies and developing new coating materials with high performance are required urgently. As such, incorporation of different surface-modification technologies with high-performance modified layers may be the mainstream of surface modifications for Ti and Ti alloys. . His current research interests focus on the metal additive manufacturing (e.g., selective laser melting, electron beam melting), titanium alloys and composites, and processing-microstructureproperties in high-performance materials.

“…Therefore, low-cost β-type Ti alloys with low-cost alloying elements, such as Cr, Mn, and Fe, are developed recently [66]. As such, many new β-type Ti alloys found their ways into biomedical fields, such as Ti-Mo-Zr-Fe series [67], Ti-15Mo-5Zr-3Al [68], Ti-15Mo-3Nb-3Al [69], Ti-12Mo-5Ta [70], Ti-Fe-Sn series [71], Ti-Fe-Ta series [72,73], Ti-Nb-Fe series [74][75][76], Ti-Zr-Fe-Cr series [77][78][79], and so on. Due to their better biocompatibility and low cost, such β-type Ti alloys would be the promising biomedical materials in the future.…”

β-type titanium (Ti) alloys have attracted a lot of attention as novel biomedical materials in the past decades due to their low elastic moduli and good biocompatibility. This article provides a broad and extensive review of β-type Ti alloys in terms of alloy design, preparation methods, mechanical properties, corrosion behavior, and biocompatibility. After briefly introducing the development of Ti and Ti alloys for biomedical applications, this article reviews the design of β-type Ti alloys from the perspective of the molybdenum equivalency (Moeq) method and DV-Xα molecular orbital method. Based on these methods, a considerable number of β-type Ti alloys are developed. Although β-type Ti alloys have lower elastic moduli compared with other types of Ti alloys, they still possess higher elastic moduli than human bones. Therefore, porous β-type Ti alloys with declined elastic modulus have been developed by some preparation methods, such as powder metallurgy, additive manufacture and so on. As reviewed, β-type Ti alloys have comparable or even better mechanical properties, corrosion behavior, and biocompatibility compared with other types of Ti alloys. Hence, β-type Ti alloys are the more suitable materials used as implant materials. However, there are still some problems with β-type Ti alloys, such as biological inertness. As such, summarizing the findings from the current literature, suggestions forβ-type Ti alloys with bioactive coatings are proposed for the future development.
