Abstract : Consideration of high pressure effects on phase equilibria and transformations from a thermodynamic point of view leads to the following conclusions: (1) in most cases quantitative thermodynamic predictions at a level of accuracy and reliability comparable to current high pressure observations cannot be carried out; (2) in cases where the nature of the high pressure phase can be directly determined or inferred with some assurance, qualitative predictions of high pressure effects can be made by the proper utilization of one atmosphere thermodynamic data; and (3) the present considerations indicate that a reiterative combination of one atmosphere thermodynamic data with high pressure observations could lead to a greater understanding of phase transformations and equilibria in metals at one atmosphere and high pressure.
