Solute Segregation in a Moving Grain Boundary: A Novel Phase-Field Approach

open access: yes, 2023
We present a novel phase-field approach for investigating solute segregation in a moving grain boundary. In our model, the correct choice of various parameters can control the solute-grain boundary interaction potential, resulting in various segregation ...

Grain boundary segregation in ordered alloys

open access: yes, 2000
Grain boundary segregation of solutes in systems with different level of the order is referred.Obtained temperature dependences of chemical composition of grain boundaries in Fe-Si, Fe-Al and NiAl systems are discussed from the point of view of present ...

Achieving superior resistance to high–temperature creep in laser powder bed fusion of Inconel 718 via grain boundaries serration

open access: yesJournal of Materials Research and Technology
Grain boundary serration and its effect on creep property in LPBF-built Inconel 718 alloy was investigated systematically. By considering the variation of the wavelength and amplitude with processing parameters, this study elucidates the evolution of the

On aluminum grain boundary structure and segregation

open access: yes, 1991
The effect of an alloying agent, such as Mg, on Al grain boundary microstructure and chemistry was investigated. HREM measurements on an Al-5% Mg Σ = 5 (310) grain boundary showed Al grain boundary structure modification because of the presence of Mg ...

Modelling grain boundary segregation in polycrystalline materials

open access: yes, 2021
The segregation of solute atoms towards grain boundaries and dislocations can severely impact the mechanical properties of alloys. Interstitial atoms can move to the dislocation cores to reduce the system energy and thus increase the force necessary for ...

Measurement and modeling of radiation-induced grain boundary grain boundary segregation in stainless steels

open access: yes, 1995
Grain boundary radiation-induced segregation (RIS) in Fe-Ni-Cr stainless alloys has been measured and modelled as a function of irradiation temperature and dose. Heavy-ion irradiation was used to produce damage levels from 1 to 20 displacements per atom (
