CALPHAD. Ni-Co-Cr. 1. Introduction. 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. Abstract. This article is a compilation of binary alloy phase diagrams for which chromium (Cr) is the first named element in the binary pair. The diagrams are presented with element compositions in weight percent. The atomic percent compositions are given in a secondary scale. For each binary system, a table of crystallographic data is provided ... In our studies the , γ andα phases exist in Cr-Ni binary phase diagram. The structures of the , γ and α phases belong to A2, A1 and , respectively.

In addition, a thermodynamic model is used to treat long-range ordering and the formation of the Ni 2 Cr. The phase field for ordering is compared against that predicted by the Thermo-Calc to elucidate possible implications on the long-term phase stability of Ni-base alloys in a nuclear waste repository environment. 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 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 ...

Abstract: The isothermal cross section through the ternary phase diagram Nb-Ni-Cr at 1,100 °C was constructed by means of diffusion couples and equilibrated alloys. It was found that nearly 28 at.% of Cr can be dissolved in the μ phase (Nb 7 Ni 6) at this temperature, and the solubility of chromium in NbNi 3 is approximately 5 at.%. Under these circumstances the low-temperature (cubic ... Predictions of the solidification phases in Cr-Ni stainless steel alloys, based on the ratio of the Cr and Ni equivalent, are shown. Incorporating these ratios into the phase solidification diagram helps to predict whether the solidification of a Cr-Ni stainless steel occurs in primary ferritic or austenitic phase. Abstract. 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, liquidus, and melting (crystallization) diagram, reaction scheme at crystallization ...

The phase diagram calculations in the quaternary Ni-Cr-Al-O system include the ceramic sub-systems Al2O3-Cr2O3, Al2O3-NiO, Cr2O3-NiO and Al2O3-Cr2O3-NiO. Gibbs free energies descriptions of the oxide solution phase (Al,Cr)2O4 and the partially inverse spinel phase Ni(Al,Cr)2O4 are developed. This spinel phase can be described with the

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 ...
