Abstract

The structural relaxation in a Pd₄₀Cu₃₀Ni₁₀P₂₀ metallic glass was investigated by an electrical resistivity experiment. A chemical short range ordering (CSRO) process was observed together with the ordinary topological short range ordering (TSRO) one. It was found that the TSRO process was influenced by the B₂O₃ flux treatment that was used to improve the thermal stability. The kinetics of CSRO were examined by measuring the isothermal change in the room temperature resistivity, ρ₃₀₀, after annealing for a given time. The data obtained were successfully fitted by the relaxation function and the CSRO process was a thermally activated process with an energy spectrum.
