Abstract:: Aluminum alloys are popular in aerospace and automotive industries because of their relatively high strength-to-weight ratio. The study of enhancing aluminum’s mechanical properties through grain refinement is especially important. One such technique is High-Pressure Torsion processing (HPT), which leads to significant grain size refinement and enhances mechanical properties like ductility...

Creator:: Ghayoor Baghbani, Seyyed Milad
Abstract:: Having a series of excellent properties, the oxide dispersion-strengthened (ODS) steels provide promising solutions for the challenges of structural materials in nuclear energy, especially the development of future advanced nuclear fission and even fusion reactors. The current manufacturing route for ODS alloys includes mechanical alloying (MA) of master alloys or...

Creator:: Saini, Jaskaran S.
Abstract:: Metallic glasses (MGs), also called amorphous metals, are metals or metallic alloys trapped in a disordered glassy state. Their amorphous nature and absence of features such as crystal lattices and defects (dislocations, grain boundaries etc.) endows them with a host of properties that far surpass those of common crystalline materials....

Creator:: Coe, Hannah G.
Abstract:: Selective laser melting (SLM) is an additive manufacturing (AM) process that uses a laser beam to melt metal powder as it is spread onto the build surface using a roller or scraper, followed by rapid solidification to manufacture a 3D component, one layer at a time. In SLM process, density...

Abstract:: The corrosion and degradation of Ni and its alloys in supercritical carbon dioxide (Sc-CO2) is an emerging issue for material selection and implementation of Sc-CO2 thermal cycles in industry. In this study, we apply density functional theory (DFT) to study the initial steps of carburization of the Ni (111) surface...

Creator:: Bowen, Michael S.
Abstract:: Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...

Creator:: Murkute, Pratik V.
Abstract:: Low carbon steels (LCS) due to their high strength-to-cost ratio are one of the most ubiquitous materials used for a wide range of applications, including but not limited to automotive, construction, and transportation. However, the low corrosion resistance of LCS in neutral, acidic, or saline environments limits its utilization and...
