Investigation of the liquidus temperature calculation method for medium manganese steel
Abstract The liquidus temperature and temperature drop coefficients of medium manganese steel were systematically studied using Factsage and differential scanning calorimetry (DSC) experiments. The results indicated that the temperature drop coefficients of C, Mn, Cr, Si, and Al were complex, while the coefficients of Mo, V, and Nb were of a constant value. Based on the temperature drop coefficients, the empirical formula for calculating the liquidus temperature of medium manganese steel was established. The liquidus temperature calculated using the empirical formula was 1422.7°C, while that obtained by the DSC experiment was 1422.9°C. By comparison with different calculation formulas, the liquidus temperature obtained from the formula that was constructed in this study was much closer to the experiment one, indicating the high accuracy of the empirical formula in predicting the liquidus temperature of medium manganese steel.
期刊介绍：
High Temperature Materials and Processes offers an international publication forum for new ideas, insights and results related to high-temperature materials and processes in science and technology. The journal publishes original research papers and short communications addressing topics at the forefront of high-temperature materials research including processing of various materials at high temperatures. Occasionally, reviews of a specific topic are included. The journal also publishes special issues featuring ongoing research programs as well as symposia of high-temperature materials and processes, and other related research activities.
Emphasis is placed on the multi-disciplinary nature of high-temperature materials and processes for various materials in a variety of states. Such a nature of the journal will help readers who wish to become acquainted with related subjects by obtaining information of various aspects of high-temperature materials research. The increasing spread of information on these subjects will also help to shed light on relevant topics of high-temperature materials and processes outside of readers’ own core specialties.
