Figure 8. One-quarter of the Debye-Scherrer diffraction patterns of the cold rolling 550 condition at (A) room temperature (RT) before aging, (B) initially reaching 550 °C, and (C) RT after the complete aging at 550 °C; Panels A, B and C are quoted with permission from Ref.^[54] . Copyright 2022, Springer Nature; (D) S(Q) curves of Ni_xAl_1-x (x = 2, 10, 20, 35, 74.5 at.%) alloy liquids obtained experimentally by HE-XRD above the liquids line temperature of 9 °C, with the arrows in the figure showing the presence of pre-peaks on the structure factor curves of Q-phase-dependent liquids, and (E) S(Q) curves at 9 °C above the liquids line temperature, where the solid lines represent experimental results and circles represent RMC simulation results.
