At 1200 °C, the fcc (Ni, Pt, Cr) phase exhibits up to approximately 66 at.%. Cr solubility with this maximum at the Cr-Pt binary.

The Ni-Co-Cr system is a key and basic system in steel, Ni-based superalloys and high-entropy alloys. Reliable thermo-chemical information of the Ni-Co-Cr system is a prerequisite for correctly predicting thermodynamic properties and phase diagrams of multicomponent systems.

The Ni-Cr-Ru phase diagram is essential in understanding the formation of sigma (σ) phase, one of the TCP phases, in Ru-bearing superalloys. The present investigation intends to determine the Ni-Cr-Ru ternary phase diagram in greater detail in order to provide more experimental data for thermodynamic modeling of the system.

PHASE RELATION Isothermal sections of the Ni-Cr-W ternary equilibrium phase diagram were experimentally determined at 1 000 and 1 loo"c. Emphasis was placed upon the nickel-rich corner of the Ni-Cr-W system.

Phase diagrams at intermediate temperatures are critical both for alloy design and for improving the reliability of thermodynamic databases. There is a significant shortage of experimental data for phase diagrams at the intermediate temperatures which are defined as around half of the homologous melting point (in Kelvin). The goal of this study is to test a novel dual-anneal diffusion multiple ...

diagrams (Schäffler and DeLong diagrams), to predict the material microstructure of stainless steel weld metals and applies those methods to LPBF manufactured Cr -Ni stainless steel (S17 - 4. 1). Predictions of the solidification phases in Cr-Ni stainless steel alloys, based on the ratio of the Cr and Ni equivalent, are shown.

For example, the composition of an Fe-Cr-Ni alloy may be described fully by stating that it contains 18% Cr and 8% ni. There is no need to say that the iron content is 74%. But the requirement that two parameters must be stated to describe ternary composition means that two dimensions must be used to represent composition on a complete phase ...

The Cu-Ni and binary phase diagram (Figure 10.3) is the simplest type of binary phase diagrams for two metals. Figure 10.3 shows that Cu and Ni are mutually soluble at room temperature throughout the entire ...

First-principles calculations of formation energies for 243 different configurations of the Cr-Ni-Re $\ensuremath{\sigma}$ phase were used to calculate a ternary phase diagram in the Bragg-Williams-Gorsky approximation (BWG) and to model finite-temperature thermodynamic properties. The binary and ternary phase diagrams were then calculated at different temperatures.

Phase equilibria of the Cr-Ni-C system in the melting (crystallization) range were investigated by means of metallography, microprobe analysis, powder x-ray diffraction, differential thermal analysis, and melting point technique (Pirani and Alterthum method). On the basis of received results and assessment of available literary data, the phase diagram was presented as projections of solidus ...
