Thermodynamic analysis of transition pressure of {delta}-stabilized binary plutonium alloys

Abstract

The transformation of {delta}-stabilized binary plutonium alloys to {alpha}-Pu was studies by thermodynamic analysis. A transition pressure-composition equation which can characterize the high pressure transformation from {delta} to {alpha} was derived. Values calculated by the equation and values measured by experiments of published references have the same tendency. the following facts can be explained properly by this equation. (1)The transformation pressure increases linearly with the amount of an alloying element. (2) The slope of the plot of transformation pressure versus composition of {delta}-Pu alloys is inversely proportional to the minimum amount of solute required to retain {delta}-phase at room temperature and pressure. (3) Curves showing the relationship between transformation pressure and composition of various {delta}-stabilized binary alloys interact at the same point of zero solute (transformation pressure axis). In addition, some transformation pressures from {delta} to {alpha} of {delta}-stabilized alloys are predicted by using the modified theoretical equation.
