Glass-forming ability and crystallization behavior of Co62−xFexNb6Zr2B30Co62−xFexNb6Zr2B30 (x=0,16)(x=0,16) amorphous alloys with large supercooled liquid region.

The kinetics of the glass transition and the crystallization process of Co 62 2 x Fe x Nb 6 Zr 2 B 30 ( x 5 0,16) amorphous alloys with large supercooled liquid region was investigated by differential scanning calorimetry. The dependence of the glass transition on the heating rate was analyzed in te...
