  • Abstract This study explores the effect of annealing temperature and time on microstructure and tensile properties of a hot-rolled medium Mn steel after two-stage annealing procedures. The results show that on the first annealing stage, annealing time gives similar microstructures and tensile properties, and on the second annealing stage, annealing time changes the grain size which altered austenite stability, therefore changes the tensile properties. Different annealing temperatures on the second stage change the volume fraction and Mn composition of austenite which in turn influence austenite stability, so that change the tensile properties.
