CO2 Alteration Rates for Class H Portland Cement
CuPd alloys are among the most promising candidate materials for hydrogen separation membranes and membrane reactor applications due to their high hydrogen permeability. In order to reduce the Pd content and, therefore, the cost of the membrane materials, efforts have been initiated to develop CuPdM ternary alloys having a bcc structure. Searching for alloying elements is done using first principles electronic density functional theory calculations. Potential ternary alloys are synthesized via arc melting, followed by a homogenization heat treatment and equilibrium annealing. The phase stability and bcc phase boundary in Cu-Pd-M systems are investigated by microstructural observation (Optical microscopy and SEM), thermal analysis, and XRD. Finally, the hydrogen permeability of promising alloys is determined.
