“…Compared with coarse‐grained materials, ultrafine‐grained materials (in submicron or nanometer) often have good physical and chemical properties, such as higher hardness, higher strength, longer fatigue life, and better low‐temperature superelasticity . Some ultrafine‐grained materials even exhibit good thermostability, high corrosion resistance, high wear resistance, and excellent biocompatibility .…”

“…As such, the ultrafine‐grained materials are expected to be the next generation of biomedical materials. So far, many different severe plastic deformation (SPD) methods have been proposed, including equal channel angular extrusion (ECAP) and accumulative roll bonding (ARB), high‐pressure torsion (HPT), multi‐directional forging, twist extrusion, cyclic‐extrusion–compression, friction stir processing (FSP) …”

Compared with stainless steel and Co-Cr-based alloys, Ti and its alloys are widely used as biomedical implants due to many fascinating properties, such as superior mechanical properties, strong corrosion resistance, and excellent biocompatibility. After briefly introducing several most commonly used biomedical materials, this article reviews the recent development in Ti alloys and their biomedical applications, especially the low-modulus β-type Ti alloys and their design methods. This review also systemically investigates the recently attractive progress in preparation of biomedical Ti alloys, including additive manufacturing, porous powder metallurgy, and severe plastic deformation, applied in the manufacturing and the influenced microstructures and properties. Nevertheless, there are still some problems with the long-term performance of Ti alloys, and therefore several surface modification methods are reviewed to further improve their biological activity, wear resistance, and corrosion resistance. Finally, the biocompatibility of Ti and its alloys is concluded. Summarizing the findings from literature, future prediction is also conducted. Darmstadt. His current research interest is focusing on the metal additive manufacturing (e.g. selective laser melting, electron beam melting), titanium alloys and composites, and processing-microstructure-properties in high-performance materials.

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.

“…In their investigation, Lu et al (2017) also found that four ECAP passes of (TiB + TiC)/Ti6Al4V composite were sufficient to produce homogeneous dispersion of TiB and TiC particles in the ultrafine grain structure. Significant grain refinements (100 nm) were attainted when 0.2 per cent B 4 C was added to (TiB + TiC)/TC18 and processed in two passes by ECAP (Wang et al , 2015c). However, sufficient recrystallization was achieved after the third pass.…”

Purpose This paper aims to present a broad review of near-a titanium alloys for high-temperature applications. Design/methodology/approach Following a brief introduction of titanium (Ti) alloys, this paper considers the near-α group of Ti alloys, which are the most popular high-temperature Ti alloys developed for a high-temperature application, particularly in compressor disc and blades in aero-engines. The paper is relied on literature within the past decade to discuss phase stability and microstructural effect of alloying elements, plastic deformation and reinforcements used in the development of these alloys. Findings The near-a Ti alloys show high potential for high-temperature applications, and many researchers have explored the incorporation of TiC, TiB SiC, Y2O3, La2O3 and Al2O3 reinforcements for improved mechanical properties. Rolling, extrusion, forging and some severe plastic deformation (SPD) techniques, as well as heat treatment methods, have also been explored extensively. There is, however, a paucity of information on SiC, Y2O3 and carbon nanotube reinforcements and their combinations for improved mechanical properties. Information on some SPD techniques such as cyclic extrusion compression, multiaxial compression/forging and repeated corrugation and straightening for this class of alloys is also limited. Originality/value This paper provides a topical, technical insight into developments in near-a Ti alloys using literature from within the past decade. It also outlines the future developments of this class of Ti alloys.
