Abstract

© 2017 IEEE. Metallic glasses (MG) are a unique class of amorphous glassy materials whose mechanical properties lie between that of metals and ceramics. Owing to their random disorganized structure, characterization of MG and ascertaining information of structure-property relationships is difficult. Ultrasonic techniques have been previously used to characterize metallic glasses either by using the time-of-flight pulse-echo technique or Resonant Ultrasound Spectroscopy (RUS). The RUS methods are however limited to certain sample types and exhaustive preparation steps.
