| Abstract Scope |
The hot deformation behavior of low carbon aluminum killed (LCAK) steel treated with mischmetals was investigated under strain rates ranging from 0.01 to 10/sec and temperatures 950 to 1250 ℃ to a true strain of 1.0. The flow characteristics were analysed based on deformation parameters. The activation energy required for the hot deformation process was estimated to be 344 kJ. The effects of microstructural changes with varying deformation parameters were examined, along with the morphological changes of rare earth-based dual-phase complex inclusions. The processing map, utilizing strain rate sensitivity (m) contours, was used to correlate with the deformed microstructure and it was found that intermediate value of m ranging from 0.10 to 0.15 should be utilized for a safe processing zone, as they ensure homogeneously distributed fine DRX grains throughout the microstructure. The extent of deformation of inclusions, along with associated cavities and cracks, was investigated across various deformation conditions. |
