Joule heating method coupled with Mössbauer spectroscopy for the study of the crystallization of amorphous ribbons

The interesting steps of the crystallization process of two types of amorphous ribbons Fe50Ni30B12Sie and Fe72Cr9Si0·3P9C10 have been detected and locked by the Joule heating method. This method reveals instantaneously with high reproductibility the various steps but Mossbauer spectroscopy seems the most adequate technique to evaluate the crystallinity rate during the crystallization process.
