摘要

The equation of state and the shear modulus data of sintered Nd2Fe14B were investigated up to 140 GPa by the Gruneisen’s model, the volume superposition principle and the Hugoniot’s relations. Then, the results were compared to the prior experiments with a standard deviation of 0.125% from 18 GPa to 78 GP;and then, the loading pressure was extended to higher. Meanwhile, the softening feature has not been observed both in adiabat and shear modulus throughout the interested range.
