“…As seen in Figure 5, the data by Hellawell and Hume-Rothery [21] on the Fe-rich side are well reproduced. Similarly, the solidus data by Kivilahti and Tarasova [23] on the Ti-rich side are well reproduced, except for the most Fe-rich alloy, which indicates a lower temperature. This indication is supported by one point by van Thyne et al [31] For the liquidus data, the calculated values are lower than the experimental information by Kivilahti and Tarasova, [23] which, however, extrapolate to a melting point for Ti considerably higher than the accepted one.…”

Thermal analysis is often used to determine equilibrium phase boundary temperatures such as the liquidus. Accurate measurements require proper calibration procedures, which are standard for given instruments. In multicomponent alloys such as RENÉ N5 and PWA1484 superalloys, a complex melting behavior associated with the solidification structure was exposed by examining the melting response at different heating rates. The observed variability in the melting signal is related to the sample processing history and is not addressed by the various standard calibration methods or supplemental procedures for different heating rates. The liquidus temperature can be determined under conditions approaching full compositional equilibrium by the application of an interrupted-heating thermal analysis protocol. The approach provides a new strategy for the reliable determination of phase boundary temperatures by thermal analysis.

“…Research shows that the main reason why the liquidus temperature of steel is lower than the melting point of pure iron is the presence of impurities and alloying elements 3. Generally speaking, there are two ways to obtain the liquidus temperature of steel for research: first, as a standard method for determining the transformation temperature of materials, a differential thermal analysis (DTA) measurement is conducted 4, and a number of studies have used DTA for the determination of liquidus temperature 5–8; second, the more common method, is to select the appropriate model according to the different kinds of steel. On the basis of the analysis of the Fe‐i binary phase diagram, a new calculation model for the liquidus temperature of steel is established in this study.…”

The liquidus temperature of steel is greatly affected by its chemical composition; therefore, the value of the liquidus temperature can vary among different types of steel. In this study, on the basis of the concept of differentiation, the Fe‐i binary phase diagram is analyzed using Photoshop image processing software. The effects of eleven common alloying elements (C, Si, Mn, P, S, Ca, Ni, Cu, Cr, Nb, and Mo, whose content is between 0%∼4%) on the melting point of pure iron are analyzed. This analysis proves the following assumption to be incorrect: the relationship between the change in liquidus temperature and the content of element i is a linear relationship; this assumption is the basis of traditional liquidus calculation models. A new model for calculating the liquidus temperature of steel is established in this study. As compared to data from other literature, the model proposed in this paper has good generality and the calculation error of the liquidus temperature of steel is between −3 and 4 °C, which is acceptable. A statistical analysis of the experimental data for different steel grades (obtained from Laiwu Special Steel) using the developed model showed that 87.2% of the absolute deviation values of the temperature are within 4 °C. This result shows the model to be both reasonable and credible.
