Determinants of Self-Interstitial Energetics in Refractory High-Entropy Alloys
Zichen Zhang, Zhiling Luo, Wang Gao +1
Self-interstitials play a central role in governing the mechanical and anti-irradiation properties of refractory high-entropy alloys (RHEAs), however, the prediction of interstitia…
An Analytic Model to Determine the Interstitial-Solute Energetics and Underlying Mechanism in Refractory High-Entropy Alloys
Qianxi Zhu, Wang Gao, Qing Jiang
The solution and diffusion of interstitial non-metallic solutes (INSs) like H, He, O, C, N, P, and S is common in refractory high-entropy alloys (RHEAs) and essentially controls th…
Analytic model for grain-boundary segregation ener-gies in metal polycrystal
Hao Wu, Xin Li, Wang Gao +1
Solute segregation at grain boundaries (GBs) of polycrystals strongly impacts the mechanical properties of metals including strength, fracture, embrittlement, and corrosion. Howeve…
Understanding the intrinsic framework of the Hall-Petch relationship of metals from the view of the electronic-structure level
Xin Li, Wang Gao, Qing Jiang
The relationship between grain size and yield strength of metals follows the Hall-Petch relationship σ = σ0 + kd^-0.5; however, the specific physical factors that affect the coeffi…
