Prediction of the Relaxation Kinetics of the Shear Modulus of Metallic Glasses during Crystallization Using Calorimetric Measurements

Abstract: The method based on Granato’s interstitialcy theory, which allows us to calculate the temperature dependence of shear modulus G using experimental calorimetry data, has been successfully tested on a number of bulk metallic glasses. The results of prediction in a wide temperature range, including the crystallization of both initial and relaxed metallic glasses, are presented for the first time. The error in calculating the temperature dependence of the shear modulus of metallic glass during crystallization does not exceed 10%.
