“…The Ti-3wt% Cu alloy is a typical hypoeutectoid alloy, and the microstructure is composed of a-Ti and Ti 2 Cu phases in the annealed state [25]. The typical band eutectoid microstructure can significantly improve the mechanical properties [26]. Particularly, the Ti-3wt%Cu alloy annealed at 400 °C for 1 h shows the YS of 612.1 MPa, the UTS of 744.1 MPa and fracture strain of 12.7%.…”

In this work, a process of cold rolling with 70% thickness reduction and different annealing temperatures was selected to regulate the microstructure of Ti-3wt%Cu alloy. Microstructural evolution, mechanical properties and antibacterial properties of the Ti-3wt%Cu alloy under different conditions were systematically investigated in terms of X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), tensile and antibacterial test. The results indicated that cold rolling could dramatically increase the ultimate tensile stress (UTS) from 520 to 928 MPa, but reduce the fracture strain from 15.3% to 3.8%. With the annealing temperature increasing from 400 to 800 °C for 1 h, the UTS decreased from 744 to 506 MPa and the fracture strain increased from12.7% to 24.4%. Moreover, the antibacterial properties of the Ti-3wt%Cu alloy under different conditions showed excellent antibacterial rate ([ 96.69%). The results also indicated that the excellent combination of strength and ductility of the Ti-3wt%Cu alloy with cold rolling and following annealing could be achieved in a trade-off by tuning the size and distribution of Ti 2 Cu phase, which could increase the applicability of the alloy in clinical practice. More importantly, the antibacterial properties maintained a good stability for the Ti-3wt%Cu alloy under different conditions. The excellent combination of mechanical properties and antibacterial properties could make the Ti-3wt%Cu alloy a good candidate for long-term orthopaedic implant application.

“…The effect of intermetallic compounds on mechanical properties of Ti-2.5Cu alloy has been widely studied [4][5][6][7][8][9][10][11]. As early as the 1970s, Williams et al [5] investigated Ti 2 Cu intermetallic compound precipitating behavior from supersaturated solid solution of Ti-Cu alloys during aging.…”

“…Moreover, Cai and Li [8] analyzed strengthening mechanisms of annealed Ti-2.5Cu alloy with Ti 2 Cu particles. The effect of nano-scale precipitates on mechanical properties of Ti-2.5Cu at room and liquid nitrogen temperatures has been studied by our group in recent years [9][10][11]. To the authors' knowledge, the precipitate behavior of Ti 2 Cu particles and its effect on strengthening of Ti-2.5Cu alloy subjected to different heat treatments have not been systemically studied, which is the objective of this work.…”

“…Sun et al. 36 attributed the longer low-cycle fatigue life at 77 K of Ti–2.5Cu alloy to its higher ductility at cryogenic temperature. In ambient conditions the dislocation substructures imply that slipping is a predominant deformation mode in cyclic deformation, but at cryogenic temperature (77 K), the twinning becomes the main deformation mode.…”

The article presents the results of an analysis of the crack growth and fatigue life of CT specimens made of explosively welded AA2519–AA1050–Ti6Al4V layered material for the construction of air and space structures. The investigations were carried out for two temperature conditions: ambient temperature (293 K) and under cryogenic conditions at the temperature of liquid nitrogen (77 K). The analysis of the test results revealed the impact of cryogenic conditions on the process of fatigue cracking of a layered material. However, this impact is partly limited by a significant scatter of the test results, which may be caused by the different character of the process of cracking.
