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 ...

MSE 2090: Introduction to Materials Science Chapter 9, Phase Diagrams 11 Isomorphous system - complete solid solubility of the two components (both in the liquid and solid phases). Binary Isomorphous Systems (I) Three phase region can be identified on the phase diagram: The thermodynamic data are incorporated into an existing database for Ni alloys and used in conjunction with the CALPHAD approach to compute the binary Ni-Cr phase diagram. 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.

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 ... 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 ... To account for the stability of the Ni 2 Cr phase and the hypothetical Ni 2 Mo and Ni 2 W phases, available thermodynamic data and ab initio electronic structure-based results were employed. A comparative study of property diagrams for the nominal composition of several YMP candidate alloys is presented.

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.
