    Development of an Ultra-Low Carbon MgO Refractory Doped with α-Al2O3 Nanoparticles for the Steelmaking Industry: A Microstructural and Thermo-Mechanical Study by Gómez Rodríguez, Cristian, Castillo Rodríguez, Guadalupe Alan, Rodríguez Castellanos, Edén Amaral, Vázquez Rodríguez, Francisco Javier, López Perales, Jesús Fernando, Aguilar Martínez, Josué Amilcar, Fernández González, Daniel, García Quiñonez, Linda Viviana, Das Roy, Tushar Kanty, Verdeja, Luis Felipe

    Published 2020
    “…However, as the α-Al2O3 nanoparticle content increased, the density and microhardness decreased. Microstructural observations showed that the presence of α-Al2O3 nanoparticles in the magnesia matrix induced the magnesium-aluminate spinel formation (MgAl2O4), which improved the mechanical resistance most significantly at 1500 °C.…”

    Corrosion behavior of AA2055 aluminum-lithium alloys anodized in the presence of sulfuric acid solution by Samaniego Gámez, Pedro Oliver, Almeraya Calderón, Facundo, Maldonado Bandala, Erick, Cabral Miramontes, José Ángel, Nieves Mendoza, Demetrio, Olguín Coca, Javier, López León, Luis Daimir, Silva Vidaurri, Luis Gerardo, Zambrano Robledo, Patricia del Carmen, Gaona Tiburcio, Citlalli

    Published 2021
    “…The Na2Cr2O7 sealing solution tends to increase the charge transfer resistance and produces a more homogeneous and compact passive oxide layer, and imparts a corrosion inhibition protection to the AA2055. SEM observations indicated that the morphology and thickness of the anodic films formed on AA2055 aluminum-lithium alloy anodized have the best results for both current densities.…”
