Structural relaxation of an “unusual” Pd40Cu40P20 metallic glass studied by measurements of the electrical resistance

Precise measurements of the electrical resistance upon thermo-cycling of an “unusual” Pd40Cu40P20 glass in the initial and cold-rolled states have been performed. The uniqueness of this glass is defined by its higher density compared to the reference tetragonal Pd2Cu2P crystal. It has been found that this glass displays the relaxation behavior, which is quite similar to that of “usual” Pd40Cu30Ni10P20 glass with the usual relationship between the densities of glassy and crystalline states.
