摘要：
We report the nonlinear elastic deformation behaviour of Ti-30Nb-12Zr alloys containing varying amounts of oxygen and/or nitrogen. These alloys feature an electron/atom (e/a) ratio of similar to 4.19, in between the eta values of two groups of multifunctional titanium alloys reported previously (Gum Metal similar to 4.24 and Ti2448 similar to 4.15), and thus demonstrate an independence of the nonlinear elasticity on the e/a ratio. This study also found that the nonlinear elasticity persists in this type metastable beta titanium alloys regardless of the presence of a small amount of other phases such as alpha, alpha '' and omega.
