【 摘 要 】

In the present investigation we have explained the thermal and compression properties of HCP iron (Fe) at high pressure with variable temperature (isobars) and at high temperature with variable pressure (isotherm). The usual Tait equation of state is modified by incorporating the effect of thermal pressure. The calculated values of pressure for different isotherms and isochors and thermal expansivity (𝛼) as a function of both temperature and pressure have been compared with those values obtained by Isaak et al and Wasserman et al.
