Effect of plastic deformation and alloying elements on the continuous cooling microstructures of HSLA steels
HSLA steel, niobium, boron, bainitic ferrite, acicular ferrite, CCT curves
Thermomechanical simulator Gleeble 3800 was used to simulate controlled hot rolling followed by a controlled cooling of some experimental heats of low-carbon Al-killed HSLA steels containing additions of different alloying elements to enhance hardenability. The continuous cooling transformation diagrams of both undeformed and thermomechanically-worked steels were monitored by dilatometry. The resultant microstructures ranged from polygonal ferrite for combinations of slow cooling rates and low alloying element contents, through to bainitic ferrite for fast cooling rates and high concentrations of alloying elements.
