The Effect of the Milling Vial Shape on the In-Situ Consolidation of a Nanocrystalline Al-Li-GNPs Nanocomposite Synthesized by Room Temperature Ball-Milling
Ahmad, Sara I.; Youssef, Khaled M. ( Frontiers Media , 2022 , Article)Several studies investigating the ball-milling of ductile face-centered cubic metals have reported a so-called in-situ consolidation phenomenon where the milled powder is also consolidated during the milling process. Thus, ... -
Efficient machine-learning model for fast assessment of elastic properties of high-entropy alloys
Guillermo, Vazquez; Singh, Prashant; Sauceda, Daniel; Couperthwaite, Richard; Britt, Nicholas; Youssef, Khaled; Johnson, Duane D.; Arróyave, Raymundo... more authors ... less authors ( Elsevier , 2022 , Article)We combined descriptor-based analytical models for stiffness-matrix and elastic-moduli with mean-field methods to accelerate assessment of technologically useful properties of high-entropy alloys, such as strength and ... -
Entropy-driven melting point depression in fcc HEAs
Tanner, Kirk; Vela, Brent; Mehalic, Seth; Youssef, Khaled; Arróyave, Raymundo ( Elsevier , 2022 , Article)High Entropy Alloys (HEAs) are an increasingly dominant alloy design paradigm. The premise of entropic stabilization of single-phase alloys has motivated much of the research on HEAs. Chemical complexity may indeed help ... -
Novel surface-treatment for bottom ash from municipal solid waste incineration to reduce the heavy metals leachability for a sustainable environment
Maryam, Al-Ejji; Hassan, Mohammad K.; Youssef, Khaled; Elmakaty, Farah; Mehanna, Hanin; Sliem, Mostafa; Irshidat, Mohammad... more authors ... less authors ( Elsevier , 2023 , Article)Unconventional treatments can provide a modification to convert ash waste into valuable materials that can be used in various applications. This study focuses on bottom ash (BA) collected from a local incineration plant ... -
Towards stacking fault energy engineering in FCC high entropy alloys
Tasneem Z., Khan; Kirk, Tanner; Vazquez, Guillermo; Singh, Prashant; Smirnov, A.V.; Johnson, Duane D.; Youssef, Khaled; Arróyave, Raymundo... more authors ... less authors ( Elsevier , 2022 , Article)Stacking Fault Energy (SFE) is an intrinsic alloy property that governs much of the plastic deformation mechanisms observed in fcc alloys. While SFE has been recognized for many years as a key intrinsic mechanical property, ...
