Recent experimental results on phase stability and deformation behavior in a multifunctional Ti-36Nb-2Ta-3Zr-0.3O alloy, Gum Metal, are summarized and its deformation mechanisms are discussed. The crystal structure of the alloy is essentially unstable to tensile loading in <110> direction, but the microstructure of the cold worked state stabilizes the crystal structure. Work hardening in Gum Metal was far smaller than the other materials even when huge amount of strain is accumulated by severe plastic deformation. By comparing actual applied stress during plastic deformation with ideal shear strength, the alloy is likely to deform at near ideal strength with stress concentrations along with the highly inhomogeneous deformation behavior.
