X-ray diffraction patterns of and recorded at HPCAT.
X-ray diffraction patterns of recorded with a beveled-anvil diamond cell at SPring8. The Pt peaks are labeled and all other peaks are from the Re gasket.
Pressure dependences of bulk , shear , and Young’s moduli from different sources. Subscript I denotes data from Ref. 9; -computed from data in Ref. 6; -computed from data in Ref. 57; -computed using and .
Typical vs plots.
Grain sizes of as a function of pressure from two different runs are shown by circles and squares. Unfilled symbols: increasing pressure; filled symbols: decreasing pressure.
Strength as a function of pressure. from Eq. (2): filled circles: sample-A, unfilled circles: sample-B. : filled circles: from Eq. (2), unfilled circles: from Eq. (6), diamonds: data from Ref. 16
Typical gamma plots for . is in angstrom units.
Pressure dependence of derived from Eq. (10) for .
The vs plot with and computed from Eq. (12).
The pressure correction for nonhydrostatic compression effect in Pt as a function of pressure. The solid and dashed lines show pressure corrections based on measured and extrapolated strengths, respectively.
The single-crystal elastic moduli (isothermal, except those marked adiabatic) and pressure derivative of Pt at ambient pressure from different sources and the derived aggregate properties. Moduli in GPa and in .
