High Nb-containing TiAl alloys exhibit exceptional high-temperature strength and room-temperature ductility, making them widely used in hot-section components of automotive aerospace engines. However, the lack accurate interatomic interaction potential for large-scale modeling severely hampers a comprehensive understanding failure mechanism Ti-Al-Nb development strategies to enhance mechanical properties. Here, we develop general-purpose machine-learned (MLP) ternary system by combining neural evolution framework with an active learning scheme. The developed MLP, trained on extensive first-principles datasets, demonstrates remarkable accuracy predicting various lattice defect properties as well characteristics such thermal expansion melting point systems. Notably, this can effectively describe key effect Nb doping stacking fault energies formation energies. Of practical importance is that our MLP enables molecular dynamics simulations involving tens millions atoms ab initio accuracy, achieving outstanding balance between computational speed accuracy. These results pave way elucidating micromechanical behaviors lamellar structures developing high-performance towards applications at elevated temperatures.
