A proper addition of Mn to Fe-C alloys could delay the isothermal transformation and change remarkably the TTT-curves to bay-like shape.The concentration of Mn at the α/γ interphase boundary and thir partition between α- and γ- phase were measured by STEM/TEM-EDAX.The results show that the partition of Mn diminishes gradually as the reaction temperature decreases.There exists a certain temperature range with the strong- est Mn concentration spike at the interphase although no Mn partition is found between austenite and ferrite,and this temperature range is correspondent with the bay-temperature on TTT curves of the alloys.It is thus suggests that the change of TTT-curve configuration is due to the partition of alloy elements.The bay-like shape is attributed to the solute drag ef- fect and the solute drag-like effect caused by the enrichment of Mn at the α/γ interphase.

On the basis of statistical data of MnS in the conventional 3% Si steel sheeets after various annealing processes,the critical inclusion factor has been evaluated to be 20 mm~(-1).The inhi- bition of MnS to grain growth has been exactly described.
