abstract = "The effect of Mn on the ferrite grain refinement has been investigated in plain 0.2%C-Mn steels after heavy warm rolling processed by the plane strain compression test with a simulated coiling. The final microstructure consists of a spheroidized cementite within an ultrafine grained ferrite matrix. It was observed that the increase in the Mn content from 0.7mass% to 1.5mass% leads to a decrease in the average ferrite grain size and to a change in the grain shape from an elongated to a more equiaxed morphology. The fraction of high-angle grain boundaries changed from 64% to 74%. The ultimate tensile strength increased from 590MPa to 680MPa, while the total elongation of 18% was the same for both materials. EDS analysis revealed an enrichment of Mn in the fine cementite particles.",
