Mechanical and microstructural properties of ultra-low carbon bainitic steel weld metal
… wire is being investigated as a consumable for Gas Tungsten Arc (GTA) and Gas Metal Arc (GMA) welding of Navy high strength (100 ksi) steels. In the present work, a candidate ULCB weld wire was investigated for GTA and GMA welding processes as a function of both welding power and cover gas. The …

Geometrically-Accurate and Homogenized Fuel Region Models to Predict Cladding Temperatures within a Truck Cask under Normal and Fire Accident Conditions
… models the geometry of the fuel rods and cover gas. Computational fluid dynamics (CFD) simulations are performed that include buoyancy induced motion in, and radiation and natural convection heat transfer across the cover gas, as well as conduction in all solid components. Separate …

Static corrosion of candidate alloys for the lead-bismuth fast reactor
… experiment. During the heating process, hydrogen gas was bubbled into the LBE, creating a highly reducing environment. Argon was used as a cover gas. Upon removal from the furnace, the alloy samples were examined via optical microscopy, scanning electron microscopy, and X-ray diffraction analysis. …

Laser weld pool optical diagnostics: Topography and visualization used for surface contour analysis and process monitoring
… thermocapillary flow, radiation pressure, cover gas flow, recoil pressure, and mass loss. Analysis shows the volume change associated with density change, the volume change associated with mass loss, and recoil pressure are the most important phenomena to incorporate into the …

Experimental simulation of crevice corrosion of a functionally graded composite system of F91 and Fe-12Cr-2Si exposed to high-temperature lead-bismuth eutectic coolant
… lead-bismuth eutectic maintained at 715*C with a cover gas of pure hydrogen for thirty hours. The conditions were kept extremely reducing, via the initial removal of oxygen and the subsequent maintenance of an environment of pure hydrogen gas, in order to simulate conditions inside a crevice. …
