| Summary: | Title screen In this study, the distributions of dislocation density with hydrogen concentration in titanium VT1-0 were obtained. The samples with different hydrogen concentrations was carried out by using the Sieverts method. The dislocation densities were obtained by using the full width at height medium calculations from the XRD results of Gaussian approximation fitting. For accurate calculation of the dislocation density in titanium alloys, the double-line separation phenomenon of the XRD results and the variation of the Burgers vector in different lattice directions were considered. The phenomenon of the double-line separation is more evident when the diffraction angle 20 is larger than 40°. The mean value of dislocation density for the different hydrogen concentrations is about 1013 ~ 1014 m-2 . Moreover, as the increases of hydrogen content in the titanium alloy, the dislocation density also increases. |
