Integrating Machine Learning and Thermodynamic Modeling for Computational Design and Optimization of Nickel-Free High-Nitrogen Stainless Steels

This dataset contains thermodynamic input parameters generated using Thermo-Calc within the CALPHAD framework for 1,152 nickel-free high-nitrogen stainless steel alloy compositions. The compositions were systematically analyzed over a temperature range of 300–1100 °C to evaluate phase stability and precipitation behavior.
