Abstract

The temperature-time-transformation curve of a Zr55Cu 30Al10Ni5 bulk glassy alloy was obtained by isothermal DSC measurements. High temperature compression tests were carried out to investigate the viscous How behavior of the Zr55Cu 30Al10Ni5 bulk glassy alloy. The influence of four process parameters (temperature, time, initial stress, strain rate) on viscous flow deformation of the bulk glassy alloy was studied. X-ray diffractometry (XRD) was used to examine a glassy state of the glassy alloy samples subjected to viscous flow deformation. Appropriate parameters of viscous flow leading to a good deformation process were proposed. The relative displacement over 80% was obtained by compressing for 200 s at 723 K under a pressure of 160 MPa with a strain rale of 1.32 × 10-2 s -1. The XRD results showed the absence of crystal peaks after viscous flow deformation under the condition being suggested.
