AB - Ultra-fine-grained dual-phase structure of AISI 1010 and Ti-Nb microalloyed steels was obtained using novel thermomechanical processing and power dissipation efficiency map. Specimens were deformed using Gleeble® 3800, maintaining a constant strain rate of 1 s−1 and total true strain of 1.4. Evolution of microstructure is investigated using optical microscopy, SEM and microtexture using EBSD. Fine-grained dual-phase structure could be obtained by careful selection of amount of strain and temperature at each step of deformation. A dual-phase ferrite + martensite microstructure with an average grain size of 3.2 µm for AISI 1010 steel and 1.1 µm for Ti-Nb microalloyed steel was obtained. These fine-grained dual-phase microstructures were obtained in the moderate power dissipation efficiency region, which points to deformation-induced ferrite formation that is supported by the flow curves.
