Abstract Scope |
The “electron wind effect” has long been cited as a potential catalyst of solid-state transformations in metals, particularly under high current densities. However, studies exploring similar effects at lower current densities, such as during Gleeble thermomechanical simulation, remain scarce. The present work compares recrystallization in cold-rolled low-carbon steel during heat treatment by conventional furnace versus direct resistance heating (Gleeble). Multiple cold reduction levels, annealing durations, and soak temperatures were examined, allowing for in-depth comparison of recrystallization activity between samples with identical furnace- and Gleeble-based thermal histories. In addition to expected trends with temperature and reduction, Gleeble annealing accelerated initial microstructural transformation relative to conventional annealing. Once recrystallized fractions saturated, microhardness and EBSD revealed convergence to equivalent behavior irrespective of heating method. JMAK analysis of recrystallization kinetics reflected the increased transformation activity during Gleeble treatment, with the value of the kinetic exponent also indicating greater grain growth activity at higher temperature. |
