Figure 3
Two-dimensional X-ray diffraction patterns showing azimuth angle (vertical axis, 0–360°) versus 2θ (horizontal axis) collected at 58 GPa from an Fe3C sample at ∼3100 K (a) and quenched from melt in ∼1 s (b), ∼0.001 s (c) and after additional annealing of (c) at ∼1600 K (d). This figure is in colour in the electronic version of the paper. |
