Based on molecular dynamics simulation, we conducted a comprehensive study on the tensile behaviors and properties of the γ(Ni)/γ(Ni3Al) superalloy with varying γ(Ni3Al) phase volume fractions (Vγ) under high-temperature, high-strain-rate service environments. Our investigation revealed that the tensile behavior of the superalloy depends critically on the Vγ. When the Vγ increased from 13.5 to 67%, the system’s tensile strength exhibited a non-monotonic response, peaking at Vγ = 40.3% before progressively decreasing. Conversely, the maximum uniform plastic strain decreased linearly and significantly when Vγ increased. These results establish an atomistically informed framework that elucidates the composition–microstructure–property relationships in γ(Ni)/γ(Ni3Al) superalloys, specifically addressing how Vγ governs variations in deformation mechanisms and mechanical performance. Furthermore, this work provides quantitative design paradigm for optimizing γ(Ni3Al) precipitate architecture and compositional tuning in the Ni-based γ(Ni)/γ(Ni3Al) superalloy. Full article
