Mechanical Testing Overview  ASTM standard (E8) used for tension testing guidance, with tests in constant displacement mode 2 tests were performed, room temperature and at 650°C Post mortem metallography was performed on both samples Room Temperature Tensile Test  Room Temperature Metallography Voids were observed in bond lines away from fracture surface. Unclear if voids were […]

Diffusion Bonding Characterization

On March 26, 2014, in

Diffusion Bond Characterization Research Goal:  Diffusion bond strength, defects, and corrosion behavior must be understood before they can be reliably used in reactor systems.           Diffusion Bond Process Plates were chemically cleaned and electroplated with nickel to prevent surface oxidation which would impair bonding process Actual process variables are proprietary to […]
