Figure 3. Azimuthally unwrapped X-ray diffraction images of quenched molybdenum.

(a) Quenched from T below the microstructure transition, showing grainy, discontinuous Mo diffraction features, signifying grain growth; (b) Quenched from T above the microstructure transition and below melting, Mo diffraction features are preferentially oriented in ϕ angle in relation to diffraction spots from MgO; (c) Quenched from T above melting, continuous Mo diffraction features, showing fine-grained, randomly oriented microstructure signifying melting. (Pressure=43(4) GPa, X-ray λ=0.4066(1) Å).
