Crystallization of glassy ${\mathrm{Fe}}_{84}{\mathrm{B}}_{16-x}{\mathrm{C}}_x$ ($x=0\mathrm{} \mathrm{to} 10$) alloys

The crystallization of glassy ${\mathrm{Fe}}_{84}{\mathrm{B}}_{16-x}{\mathrm{C}}_x$ ($x=0\mathrm{} \mathrm{to} 10$) has been studied with differential-scanning-calorimetry, electrical-resistivity, low-field-magnetization, Mössbauer-spectroscopy, and transmission-electron-microscopy measurements. A crystallization process is suggested by these data, and it is shown that all the data are at least consistent with or explained by this process. It is noted that the carbon addition does not merely produce a compositional change, but a structural change as well.
