摘要
The compression behavior of Ni77P23 amorphous alloy is investigated at room temperature in a diamond-anvil cell instrument using insitu high pressure energy dispersive X-ray diffraction with a syn- chrotron radiation source. The equation of state is determined by fitting the experimental data accord- ing to Birch-Murnaghan equation: -ΔV/V0=0.08606P-3.2×10-4P2+5.7×10-6P3. It is found that the structure of Ni77P23 amorphous alloy is stable under pressures up to 30.5 GPa.
The compression behavior of Ni77P23 amorphous alloy is investigated at room temperature in a mond-anvil cell instrument using in-situ high pressure energy dispersive X-ray diffraction with a synchrotron radiation source. The equation of state is determined by fitting the experimental data according to Birch-Murnaghan equation： -△V/V0=0.08606P-3.2×10^-4P^2＋5.7×10^-6P^3. It is found that the structure of Ni77P23 amorphous alloy is stable under pressures up to 30.5 GPa.
