Abstract

The Ni50Pd30P20bulk metallic glass was produced by flux treatment and casing. The formation of a glassy structure of the studied alloy was confirmed by X-ray diffractometry and transmission electron microscopy. Its deformation behavior under uniaxial compression at room temperature was studied at the strain rate of 5 × 10-4s -1as well as at three different strain rates at the quasistatic loading conditions. The serrated flow behavior appears to be chaotic and is analyzed with a stochastic model. The model suggests that the underlying serrated slow dynamics initially results from the appearance of new shear bands in the material, but as the experiment proceeds the nature of these dynamics change, and strain takes place by the enlargement of shear bands already present on the material.
