In this paper,we carried out experimental studies on the influence of the strength of materials on the pressure calibration under non-hydrostatic compression using the diamond anvil cell and synchrotron radiation X-ray diffraction technology.Pt and Au were used as the pressure marker in the same high pressure cavity.Pt calibrates the cavity pressure,and Au mixed with β-SiC or NaCl powder calibrates the pressure ofβ-SiC and NaCl powder.The pressure was loaded to 50 GPa,respectively.Our experimental results i...
