摘要：

Structural properties at 30 K of Fe64Ni36 and Fe72Pt28 Invar alloys have been investigated through x-ray diffraction experiments up to 20 GPa. The Invar magnetovolumic characteristic property clearly affects the equation of state of both Fe-Ni and Fe-Pt samples between 2 and around 6 GPa. A fit function based on the 2-gamma state model is used to analyze our (p,V,T) data and is shown to be suitable to interpret them.
