Domain-wall energy governs coercivity in ordered and disordered additively manufactured Fe--49Co--2V
Dennis Boakye, Chuang Deng
Additively manufactured soft-magnetic Fe--Co is consistently harder than wrought material of the same composition, and controlling that excess is the central obstacle to printing e…
Solidification-cell confinement of domain-wall pinning in additively manufactured ferromagnets
Dennis Boakye, Eric K. K. Abavare, Chuang Deng
As-built printed ferromagnets typically exhibit higher coercivity than optimized wrought materials, yet existing explanations rely on empirical fits or costly simulations. Herein,…
Dominant-pair free energies predict phase selection in high-entropy alloys
Dennis Boakye, Chuang Deng
Phase selection in multicomponent alloys is governed by the competition between entropic stabilization of disordered solutions and enthalpic driving forces for chemical ordering. H…
Predicting co-segregation in alloys with solute-solute interactions
Zuoyong Zhang, Chuang Deng
The co-segregation of impurities in systems with multiple solute species has been widely recognized as an effective strategy for tailoring material properties. However, reliable pr…
Rapid modeling of segregation-driven metal-oxide adhesion in high-entropy alloys using macroscopic atom model
Dennis Boakye, Chuang Deng
Accurate prediction of metal-oxide adhesion in high-entropy alloys (HEAs) is challenging because interfacial segregation, atomic environments, and macroscopic thermodynamic quantit…
Disconnection formation via segregation-induced grain boundary phase transitions
Zuoyong Zhang, Chuang Deng
Disconnections, long recognized as the key mediators of grain boundary (GB) kinetics in polycrystalline materials, have traditionally been understood to nucleate through thermal or…
Grain boundary interstitial segregation in substitutional binary alloys
Zuoyong Zhang, Chuang Deng
Grain boundary (GB) segregation is a powerful approach for optimizing the thermal and mechanical properties of metal alloys. In this study, we report significant GB interstitial se…
Grain boundary segregation prediction with a dual-solute model
Zuoyong Zhang, Chuang Deng
Solute segregation along grain boundaries (GBs) profoundly affects their thermodynamic and kinetic behaviors in polycrystalline materials. Recently, the spectral approach has emerg…
