Room-temperature XRD results for solution treated (ST) (a), cold rolled plus annealed (CRA) (b) Ti-33Nb-4Sn specimens and XRD results obtained at 473 K for the ST Ti-33Nb-4Sn specimen (c). Notice the appearance (a) and absence (b) of α″-martensite in the ST and CRA specimens, respectively. Evidence for α-phase can be identified in (b). Only β-peaks are present at 473 K (c).
