XRD patterns of Ce₃Al at high pressures and 298 K using X-ray wavelength λ = 0.3681(1) Å. (A) Starting with a metallic glass, the transition occurs at 25 GPa. Intensity mismatch to the fcc structure is caused by the growth of large crystals in our sample. (B) Starting with hexagonal α-Ce₃Al, the transition occurs at 15 GPa.
