From: New intrinsic mechanism on gum-like superelasticity of multifunctional alloys
High-energy X-ray diffuse scattering (HE-XRDS) studies of phase transition kinetics and microstructural features for different phases for gum-type Ti-24Nb-4Zr-8Sn-0.10O single crystal.
(a), Volume fraction of ordered α" phase as a function of applied stress. (b), The domain size and full-width at half maximum (FWHM) for 
scattering peak of frustrated α" martensite as a function of applied stress. (c), The change in lattice strain obtained from (220)β for β phase and frustrated δ martensite and (040)α″ for α″ martensite as a function of applied stress. (d), The FWHM for β, δ and α" phases as a function of applied stress. The inset in (b) is the scattering patterns of 
at different transformation stages. Note the change of cell volume from β to frustrated δ martensite under a tensile loading stress in (d).
