Free volume and elastic properties changes in Cu–Zr–Ti–Pd bulk glassy alloy on heating

The variation of free volume and elastic properties of the Cu55Zr30Ti10Pd5 glassy alloy on heating was studied. The structure changes on heating were studied by synchrotron X-ray diffraction, differential scanning and isothermal calorimetries. The studied glassy alloy shows a rather high Poisson's ratio exceeding 0.42 which is maintained after the structure relaxation and primary devitrification. Young's and Shear modules decrease upon primary devitrification while Bulk modulus exhibits a maximum after structural relaxation.
