| Abstract: | Gum Metal stands for a group of multifunctional titanium alloys those satisfy certain special magic electronic parameters and chemical compositions. These alloys exhibit a series of unique properties, such as superplasticity and low work hardening ratio at room temperature, and high strength, nonlinear superelasticity, low elastic modulus, Invar and Elinvar behavior after severe cold deformation. The unique properties and deformation mechanism have been disputed seriously since the alloys were developed. In this paper, by integrating our research work, the progress in research of Gum Metal is reviewed from the aspects of alloy design, preparation process, properties, composition sensitivity and plastic deformation behaviors. |
