In this study, we propose a machine learning approach to predict the fracture strain of RHEAs. A dataset comprising 128 RHEAs fracture strain samples is compiled from the literature and classified into two categories: “high plasticity” and “low plasticity.” Through feature selection techniques, a critical subset of features is identified, enabling a support vector classification model to achieve 96% prediction accuracy. Additionally, an interpretable machine learning algorithm is employed to derive explicit functional expressions describing the relationship between key features and fracture strain, achieving 88% accuracy.

During the electric field-driven polarization switching process, the domain wall is immobile. Importantly, we observe that a distinct domain structure spontaneously forms in bulk lead zirconate upon annealing at 300 K.

Machine learning models were applied to predict mechanical properties, in which random forest (RF) model exhibited the best performance and further validated by a new experimental sample of Zn-0.05Mg-0.5Mn, with the mean absolute percentage error (MAPE) less than 10%.

Finally, by combining multi-objective genetic algorithm and RF models, the optimization alloy composition and extrusion parameters was carried out, targeting high-strength, strength/plasticity synergy, and high plasticity for biodegradable purpose. A notable optimized scheme for strength/plasticity synergy in Zn-0.20Mg-0.60Mn (wt.%) achieves the YS of 303 MPa, UTS of 354 MPa, and EL of 25.1% with the MAPE less than 10%, and exhibits the strain-hardening response, associated with ER of 16, ET of 170°C, and ES of 3.21 mm/s.
