Activation volume of microscopic processes in amorphous Pd77.5Cu6.0Si16.5 due to stress and temperature
Source abstract
Abstract
Abstract Creep/recovery measurements of amorphous PdCuSi ribbons have been performed. From these data we calculated the activation volume of relaxation processes in the temperature range from the glass transition temperature (Tg) to crystallization. The results indicate a correlation between applied stress and the activation volume of clusters in temperature regime close to Tg. With these results it is possible to compare molecular dynamic simulations for microscopic loss processes in metallic glasses with experimental values for mobile clusters.
