| Abstract Scope |
The strengthening of interstitial-free steel is the key focus of the present study. The samples have been soaked in the austenitic temperature domain for homogenization followed by furnace-cooling, air-cooling, and water-quenching in a Gleeble 3800 thermomechanical simulator. The outcome shows a dramatic increase in tensile strength along with a decent ductility in the water-quenched sample. As the reason, electron microscopy analysis has revealed the lath type morphology with high dislocation density. Further, the image-quality map, grain-boundary misorientation and Kurdjumov-Sachs orientation relationships with parent austenite confirm martensite in the interstitial-free steel by water-quenching, as the novel finding. |
