Kuvaus

The structures and energetics of CuNiPd ternary alloys were studied by the ab initio-based cluster expansion method and compared to the results of experimental studies. It is demonstrated that the environments of Ni and Pd remains unchanged when going from dilute Cu1-xatomx to Cu1-xNi0.5xPd0.5x, with Ni forming pure Ni phase and Pd being coordinated by 12 Cu atoms. In Cu57Ni1Pd42, a phase transition β(ordered)→γ(disordered) occurs at approximately 865 K. There are no ordered ternary compounds in the fcc or bcc lattice at 0 K.
