Description
Summary:Titanium alloys are receiving a big attention for biomedical applications. Recently, b type titanium alloys composed of non-toxic elements are being developed for these applications. The aim of this paper is to study mechanical properties and deformation mechanisms of three beta titanium alloys designed with similar values of Bo-Md and e/a ratio. The contribution of electronic approach to predict beta phase stability is also discussed. The microstructural analysis and the mechanical characterization are carried out for different metallurgical states (cold working, solution treatment and aging treatment). Effects of aging treatment at low temperature is also investigated, showing that isothermal holding at 400°C for 0,6 ks after cold working improves the mechanical properties of alloys.
