THE NEW COLD-WORK PEAKS IN LOW CARBON AND INTERSTITIAL-FREE STEELS

Abstract
A new peak at 210~220 K (~1 Hz) for a low carbon steel and an interstitial free steel and another peak at 170K (~1 Hz) for the interstitial free steel were observed for heavy plctstic-deformed specimens. Those peaks exhibit an anomalous dependence of strain amplitude and an aging effect. The main characteristics of these peaks are interpreted in terms of intrinsic motion of high dislocation density due to high internal residual stress.
