Calculation of Ni–Cu, Ni–Ag, and Cu–Ag Phase Diagram Using CALPHAD Method
摘要
MATLAB is a powerful tool for scientific computing, offering seamless integration of computation, representation, and computer programming within an intuitive surrounding. Using well-known mathematical symbols and expressions, users can effectively express and solve complex problems, including calculating phase diagrams. The present work introduces a MATLAB-based approach for constructing collective a tangent between Intersection curves, specifically applied to the Ni–Cu, Ni–Ag, and Cu–Ag phase diagrams. This paper describes the underlying principles and presents a detailed flowchart for implementation, offering a valuable resource for researchers and practitioners in materials science and related fields. The computed melting temperatures for Ni, Cu, and Ag are 1728 K, 1356 K, and 1235 K, respectively, which align well with existing data. Notably, the model identifies the maximum solubility of copper in silver as 14.07%. These results highlight the model's efficacy for predicting phase diagrams in more complex systems, offering valuable materials science and engineering insights.
