Abstract
Ti-13Nb-13Zr-7Ag (TNZ-7Ag) has a great potential for biomedical application due to its low elastic modulus and excellent antibacterial properties. However, it is difficult to balance low elastic modulus and high antibacterial properties. In this study, the TNZ-7Ag was treated by a pre-deformation and aging treatment to avoid this problem. The results proved that the stress-induced twinning caused a large range of Ti2Ag particle agglomeration, and in turn enhanced the antibacterial performance of Ag-containing titanium alloys. And the twinned martensite formed during the pre-deformation promoted the precipitation of Ti2Ag phase and inhibited the growth of α phase. As a result, TNZ-7Ag with both low elastic modulus and strong antibacterial properties was obtained by the treatments. All results demonstrated that pre-deformation based on the synergistic effect of aging treatment was an effective strategy to develop novel biomedical titanium alloys. Low-elastic-modulus antibacterial titanium alloys, which can be used for the development of novel biomedical titanium alloys, were prepared.
期刊介绍:
Metals (ISSN 2075-4701) is an open access journal of related scientific research and technology development. It publishes reviews, regular research papers (articles) and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Metals provides a forum for publishing papers which advance the in-depth understanding of the relationship between the structure, the properties or the functions of all kinds of metals.
