Abstract There could be found any fine inclusions containing Mg whose sizes were less than 300nm.To study the function of the inclusions containing Mg during TMCP rolling art, The hot rolling simulation art was carried out on Gleeble-3800.in X120 pipeline steel with Mg treatment. It was found that the inclusions containing Mg could act as the nucleuses of fine deformed austenite during rolling, and also as the nucleuses of intragranular ferrite during transformation process from austenite to ferrite where the size of austenite was within 20µm and even 10µm. It also found the function of the inclusions during the solid transformation.
