摘要：
An X-ray analysis method was used to investigate alloying element accumulation at the austenite-ferrite boundaries in an Fe-C-Mo alloy. Heat treatment of the austenitized sample fell within the incomplete transformation regime of the alloy. The accumulation of molybdenum (Mo) at γ-α boundaries was analyzed. The result was interpreted in terms of thermodynamic excess of solute at the interface.
