摘要We perform the high-pressure energy dispersive x-ray diffraction experiments of nickel nanoparticle chain using a synchrotron source under quasi-hydrostatic compression up to 44.7GPa. There is no phase transition over the pressure range. The bulk modulus K0, the first pressure derivative of bulk modulus K0' and the volume V0 are calculated from the pressure--volume data using the Birch--Murnaghan equation of state. A decrease of compressibility is observed, in agreement with the Hall--Petch effect.
