Abstract
We have measured acoustic emission (AE) in commercially available silicate and metallic glasses while heating through the glass temperature (
T
g). In silicate glasses AE is emitted at
T
g which may be due to free volume diffusing to the surface. In amorphous Fe

6 tapes the AE and self twist (ST) show a strong correlation in three distinct regions. Region 1 (150–225°C) is probably caused by the production process, ie secondary cooling. Region 2 (225–325°C) is probably due to structural relaxation. Crystallization occurs in Region 3 (325–450°C). The AE and ST are both irreversible when the sample is reheated to any specific temperature. The effects of varying stress levels and magnetic field are also examined. Stress relief is observed by AE measurements during an isothermal anneal.
