Diffraction patterns from titanium samples BT1-0 in the state of delivery (a) and after rolling at T = 293 K (b) and T ≈ 110 K (c) up to deformation ɛ = 1.9. At small reflection angles the diffusion halo is observed.
The dark-field TEM image with an electron micropattern (a) and the histogram of size distribution of grains (b) in titanium after cryodeforamtion up to ɛ = 1.95.
The bright-field TEM image and electon diffraction micropattern for titanium, rolled at room temperature (ɛ ≈ 1.4).
The bright-field with electron diffraction micropattern (a) and dark-field (b) TEM images of titanium, rolled at room temperature up to ɛ ≈ 1.4 (the site neighboring with that shown in Fig. 3).
The histogram of size distribution of RCS for titanium, rolled at room temperature.
The dependence of an integral intensity of diffraction maxima and diffusion halo on the annealing temperature.
The diffraction patterns of titanium BT1-0, rolled at T ≈ 110 K (a) and subsequently annealed at T, K: 523 (b), 723 (c) and 923 (d).
