Tensile properties and microstructure of additively manufactured Grade 91 steel for nuclear applications Eftink, Benjamin P.; Vega, Daniel A.; El Atwani, Osman; Sprouster, David J.; Yoo, Yung Suk J.; Steckley, Todd E.; Aydoğan Güngör, Eda; Cady, Carl M.; Al-Sheikhly, Mohamad; Lienert, Thomas J.; Maloy, Stuart A. (Elsevier BV, 2021-02-01) © 2020 Elsevier B.V.Laser powder bed additively manufactured Grade 91 composition steel was investigated in comparison to wrought Grade 91 steel in terms of microstructure and mechanical properties. As-deposited additively...
In Situ Micro-Pillar Compression to Examine Radiation-Induced Hardening Mechanisms of FeCrAl Alloys Cui, Yuchi; Aydoğan Güngör, Eda; Gigax, Jonathan G.; Wang, Yongqiang; Misra, Amit; Maloy, Stuart A.; Li, Nan (Elsevier BV, 2021-01-01) © 2020The effects of 5 MeV Fe2+ ion irradiation at 300°C on the microstructure evolution and deformation behavior of a FeCrAl C26M alloy are presented. It has been found that dislocation loop density increases an order of ...
In-situ observation of nano-oxide and defect evolution in 14YWT alloys Aydoğan Güngör, Eda; El-Atwani, O.; Li, M.; Maloy, S.A. (Elsevier BV, 2020-12-01) © 2020 Elsevier Inc.Nanostructured ferritic alloys (NFAs) are considered as candidates for structural components in advanced nuclear reactors due to their excellent radiation resistance as a result of a high density of nan...
Damage relief of ion-irradiated Inconel alloy 718 via annealing Fincher, Cole D.; Turman, Haley; French, Aaron; Chancey, Matthew; Gigax, Jonathan; Aydoğan Güngör, Eda; Zhao, Dexin; Yadav, Digvijay; Xie, Kelvin; Wang, Yongqiang; Borden, Mike; Shao, Lin; Maloy, S. A.; Pharr, Matt (Elsevier BV, 2020-09-01) Inconel alloy 718 is a high-strength and corrosion resistant alloy that is commonly used as a beamline vacuum window. The accumulation of irradiation-induced damage substantially decreases the window's service lifetime, an...
alpha ' formation kinetics and radiation induced segregation in neutron irradiated 14YWT nanostructured ferritic alloys Aydoğan Güngör, Eda; Martinez, E.; March, K.; El-Atwani, O.; Krumwiede, D. L.; Hosemann, P.; Saleh, T.; Maloy, S. A. (Springer Science and Business Media LLC, 2019-06-01) Nanostructured ferritic alloys are considered as candidates for structural components in advanced nuclear reactors due to a high density of nano-oxides (NOs) and ultrafine grain sizes. However, bimodal grain size distribut...
Response of 14YWT alloys under neutron irradiation: A complementary study on microstructure and mechanical properties Aydoğan Güngör, Eda; Weaver, J. S.; Carvajal-Nunez, U.; Schneider, M. M.; Gigax, J. G.; Krumwiede, D. L.; Hosemann, P.; Saleh, T. A.; Mara, N. A.; Hoelzer, D. T.; Hilton, B.; Maloy, S. A. (Elsevier BV, 2019-04-01) Nanostructured ferritic alloys (NFAs) having sub-micron grain size with a high density of nano-oxides (NOs) (size of similar to 2-3 nm) are one of the best candidates for structural components in Generation IV nuclear syst...
Impact of composition modification induced by ion beam Coulomb-drag effects on the nanoindentation hardness of HT9 Gigax, Jonathan G.; Kim, Hyosim; Aydoğan Güngör, Eda; Price, L. M.; Wang, X.; Maloy, S. A.; Garner, F. A.; Shao, L. (Elsevier BV, 2019-04-01) Accelerator-based ion irradiation is commonly used to simulate neutron damage, in lieu of neutron irradiation due to limited availability of fast flux facilities and little to no activation of the samples. Neutron atypical...
Effect of High-Density Nanoparticles on Recrystallization and Texture Evolution in Ferritic Alloys Aydoğan Güngör, Eda; Rietema, Connor J.; Carvajal-Nunez, Ursula; Vogel, Sven C.; Li, Meimei; Maloy, Stuart A. (MDPI AG, 2019-03-01) Ferritic alloys are important for nuclear reactor applications due to their microstructural stability, corrosion resistance, and favorable mechanical properties. Nanostructured ferritic alloys having a high density of Y-Ti...
Unprecedented irradiation resistance of nanocrystalline tungsten with equiaxed nanocrystalline grains to dislocation loop accumulation El-Atwani, O.; Esquivel, E.; Aydoğan Güngör, Eda; Martinez, E.; Baldwin, J. K.; Li, M.; Uberuaga, B. P.; Maloy, S. A. (Elsevier BV, 2019-02-01) Nanocrystalline metals are often postulated as irradiation tolerant materials due to higher grain boundary densities. The efficiency of these materials in mitigating irradiation damage is still under investigation. Here, w...
Microstructure and mechanical properties of FeCrAl alloys under heavy ion irradiations Aydoğan Güngör, Eda; Weaver, J. S.; Maloy, S. A.; El-Atwani, O.; Wang, Y. Q.; Mara, N. A. (2018-05-01) FeCrAl ferritic alloys are excellent cladding candidates for accident tolerant fuel systems due to their high resistance to oxidation as a result of formation of a protective Al2O3 scale at high temperatures in steam.
