Deconvoluting Mechanisms of Radiation-Induced Grain Boundary Segregation in Dilute Ni-X (X = Fe, Cr, Mn) Alloys via Ion Irradiation and Phase-field Modeling
Sohail Shah, Sourabh Bhagwan Kadambi, Anshul Kamboj +7
Radiation-induced composition redistribution at grain boundaries (GBs) in Ni-based structural alloys poses a critical challenge for the long-term deployment of advanced nuclear rea…
Radiation-induced segregation in dilute Fe-Cr: A rate-theory framework for the Cr enrichment-depletion transition at the grain boundary
Russell Oplinger, Mukesh Bachhav, Karim Ahmed +1
Radiation-induced segregation (RIS) poses a significant challenge for ferritic Fe-Cr alloys under irradiation, as it can compromise mechanical integrity and increase susceptibility…
Phase-field modeling of radiation-induced composition redistribution: An application to additively manufactured austenitic Fe-Cr-Ni
Sourabh Bhagwan Kadambi, Daniel Schwen, Jia-Hong Ke +2
Multicomponent alloys undergoing irradiation damage develop radiation-induced composition redistribution at point defect sinks such as grain boundaries (GBs) and dislocations. Such…
Vacancy-mediated transport and segregation tendencies of solutes in FCC nickel under diffusional creep: A density functional theory study
Shehab Shousha, Sourabh Bhagwan Kadambi, Benjamin Beeler +1
The Nabarro-Herring (N-H) diffusional creep theory postulates the vacancy-mediated transport of atoms under a stress gradient as the creep mechanism under low-stress and high-tempe…
Phase Boundary Segregation in Multicomponent Alloys: A Diffuse-Interface Thermodynamic Model
Sourabh Bhagwan Kadambi, Srikanth Patala
Microalloying elements tend to segregate to the matrix-precipitate phase boundaries to reduce the interfacial energy. The segregation mechanism is emerging as a novel design strate…
A phase-field approach for modeling equilibrium solute segregation at the interphase boundary in binary alloys
Sourabh B Kadambi, Fadi Abdeljawad, Srikanth Patala
A number of experimental and theoretical findings in age hardening alloys suggest that specific solute elements preferentially segregate to and reduce the energy of the interphase…
Thermodynamic Stabilization of Precipitates through Interface Segregation: Chemical Effects
Sourabh B Kadambi, Srikanth Patala
Precipitation hardening, which relies on a high density of intermetallic precipitates, is a commonly utilized technique for strengthening structural alloys. Structural alloys are c…
