Abstract Scope |
RMPEAs have recently attracted increasing attention due to their outstanding mechanical properties. The microstructure and mechanical properties of RMPEAs are greatly affected by their phase distribution. However, the extensive compositional range of RMPEAs makes it impractical to investigate their phase stability with traditional methods. We present a deep learning framework that accurately predicts RMPEA phase fractions. Our training dataset comprises several hundred thousand RMPEAs, each containing 17 elements with varying atomic percentages. These alloys are labeled by a comprehensive set of 43 chemistry-based features, chosen to improve the accuracy of phase predictions. The expected RMPEA phases are determined using CALPHAD at seven different temperatures. Performance of the trained framework is further optimized using a large set of experimental datasets. Subsequently, a high-throughput method is employed to optimize the bcc phase fraction across the compositional range. Finally, a mathematical equation is derived that enables the precise separation of single-phase BCC RMPEAs. |
