- Abstract
Based on a two-stage multi anvil apparatus, with diamond anvil cell device, combined with the high-pressure in situ X-ray diffraction (XRD) technology of Beijing Synchrotron Radiation Light Source, the phase transitions and grain size variation behaviors of germanium under high pressure were systematically investigated. It is found that the reciprocating phase transitions indeed have obvious effects on the grain refinement of germanium. At the same time, the amorphous regions are found in the bulk samples that have undergone five times reciprocating phase transitions, which provides a new way for the preparation of nanostructured and amorphous materials.
