The concentration of Mn at α/γ in-terfaces and their neighboring matrix were measured by STEM / EDAX. The results show that the partition of Mn between α and γ occurs at higher temperature but not at lower temperature. There exists certain temperature range with the strongest Mn concentration spike at the inter-face even though Mn partition between α and γ is not found at the temperature on range. The fact that temperature at which the highest Mn concentration spike occurs is correspondent with the bay temperature on TTT curves shows that the change of TTT curve shape is due to the solute drag effect and solute drag--like effect which are caused by the enrichment of Mn at the α/γ interface. Key words:  TTT curve      partition      Mn      Fe-C alloy      solute drag      Received:  18 January 1992      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1992/V28/I1/16 1 Coates D E.
