New high-pressure phase transition in zirconium metal

Academic Article


  • Phase transitions in the group-IV transition-metal zirconium were studied by the energy-dispersive x-ray-diffraction technique with a synchrotron source to a pressure of 32 GPa. A first-order phase transition between an phase and a bcc phase (isostructural with group-V transition elements) was observed during compression and decompression in a pressure range of 30+2 GPa, which is in qualitative agreement with the recent first principles theoretical predictions. The observation of the bcc phase in Zr (a group-IV element) under pressure at room temperature signifies a pressure-induced electronic configuration similar to that of a group-V element. © 1990 The American Physical Society.
