Thermodynamic modeling of the Cr-Pd and Mo-Pd systems

To assist the quantitative design of ultra-high strength (UHS) quantum stee ls containing Pd, a set of self-consistent thermodynamic model parameters i s presented to describe the phase equilibria of the Cr-Pd and Mo-Pd systems , These thermodynamic parameters are of importance to control the kinetics of solid-solid phase transformations, such as martensitic transformation, a nd precipitation of M2C carbide and austenite, relevant to the design of UH S steels in the Fe-C-Co-Cr-Mo-Ni-Pd system. The present thermodynamic model ing complements our previous report on the thermodynamic modeling of the Co -Pd, Fe-Pd, and Ni-Pd systems to facilitate quantitative design of UHS quan tum steels.
