Sandia’s Supercritical Carbon-Dioxide/Brayton-Cycle Laboratory Signs Important MOU with Industry Partners

Sandia and eight other companies and research organizations* will collaborate to advance a distributed power system that can produce cleaner, more efficient electricity. The memorandum of understanding (MOU) focuses on developing an energy-conversion system based on supercritical carbon dioxide (sCO2)/Brayton-cycle technology. Gary Rochau, manager of Sandia’s Advanced Nuclear Concepts Dept. said sCO2/Brayton cycle technology could [...]

Diffusion Bonding Characterization

Research Goal 1. Tensile specimens prepared from diffusion-bonded block of 316/316L SS2. Micrograph showing good grain growth across the diffusion bond3. Small defects in bond area may not impact overall strength—but could lower design life, due to crevice corrosion Diffusion bond strength, defects, and corrosion behavior must be understood before they can [...]
