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…
Correlating Local Lattice Distortion with Dislocation Pinning in Refractory High-Entropy Alloys
Zhiling Luo, Wang Gao, Qing Jiang
Local lattice distortion (LLD) of refractory high-entropy alloys (RHEAs) plays an essential role in mechanical properties and phase stability. However, the random distribution of m…
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 Ï = Ï0 + kd^-0.5; however, the specific physical factors that affect the coef…
