Study, in pilot plant, of the relationship process, microstructure and properties of microalloyed steels processes by conventional and thermomechanical rolling

Abstract:

The influence of the thermomechanical parameters and microalloying elements on the relationship between process, microstructure and properties of DIN 20MnCr5 steel plates was the objective of this work. The tests were developed on a pilot scale, at IPT metallurgical process laboratory. Variations of chemical composition, rolling conditions and cooling rates were tested. It was observed elongations of austenitic grains for the materials processed by thermomechanical rolling and grain refinement and increase of yield strength for microalloyed steels at both conventional and thermomechanical rolling conditions.
