✦ Synopsis

Amorphous structure was detected in surface layer of a medium carbon steel sample impacted with repeated load. With HRTEM, it was observed that the deformation-induced amorphous more appeared on the internal surface of microcrack. Through thermodynamics calculation, it can be proved that the microcrack surface is a preferred site for deformation-induced amorphous, and the main driving force is interfacial energy instead of dislocation energy.
