Metallurgical considerations of Pd, Pd-alloy and metal-hydrogen systems

Pd-Alloy membranes for hydrogen separation

“…Alloying Pd with Ag [39,40], Ni [41], or Pt [42] can, for example, lower the critical temperature of Pd's a-b phase transition and lower the extent of lattice expansion that accompanies the transition [8]. Alloying Pd with Y, Cu, or Ru increases its hardness and ultimate tensile strength [43].…”
