Figure 5
In situ 2D Raman mapping of polycrystalline powders after 90 min of milling (βαβ). The horizontal and vertical coordinates represent the position of the micro-region characterized by Raman spectra, and the scale is the ratio of the peak intensity between 782 and 762 cm−1. Red and blue represent the pure β and α forms, respectively.
