| Abstract Scope |
The recrystallization of metallic materials can be effectively achieved through the direct electric current-assisted electro-treatment. In this study, the microstructure and mechanical property of cold-rolled pure Fe strips were investigated using electron backscattered diffraction (EBSD) and X-ray diffraction (XRD) techniques for the electro-treatment effects. Electro-treatment at an applied current density of up to 2.95*10^4 A/(cm)^2 for 1 h duration resulted in a significant micro-hardness reduction with a 49.6% decrement, accompanying the progressive recrystallization and grain growth phenomena. Furthermore, the texture analyses using orientation distribution functions (ODFs) provided more solid evidence of recrystallization in a cold-rolled body-centered cubic (BCC) metal, revealing preferred texture transformation from a cold-rolled texture ({113}<110> α fiber and {111}<110> γ fiber) to a recrystallized one ({111}<121> and {111}<110> γ fibers). The contributions of thermal and athermal effects from the electro-treatment on triggering recrystallization were also evaluated by conducting a series of thermal benchmark experiments. |
