Abstract:
Disclosed are methods and apparatus for determining an unknown degree of amorphicity in a bulk-solidifying amorphous alloy. A specimen can be prepared from the alloy, irradiated with passive radiation, imaged to provide a thermal image, and the image analyzed to assess the differences in emissivities in the image. The degree of amorphicity can be determined based on the differences in thermal emissivities.
