Abstract Using a high-temperature confocal laser scanning microscope, in-situ observation of the peritectic transformation phenomenon during the soli-dification process of peritectic steel and peritectic steel containing Mg-Ti was carried out. During the phase transition from L to δ, the number and size of δ phase precipitated from the L phase in peritectic steel containing Mg-Ti were smaller than those in peritectic steel without Mg-Ti. In the peritectic reaction stage, the starting temperature of the peritectic reaction of peritectic steel containing Mg-Ti was 12.3 ℃ lower than that of peritectic steel without Mg-Ti, which reduced the formation temperature of phase γ and inhibited its growth. The shrinkage of peritectic transformation should lead to an increase in surface roughness. Through surface roughness measurement, it was found that the surface roughness of peritectic steel containing Mg-Ti was reduced by 10% compared to peritectic steel without Mg-Ti. The solidification shrinkage characteristic index (R_V) calculation found that under equilibrium and non-equilibrium solidification conditions, the solidification shrinkage characteristic index of peritectic steel containing Mg-Ti decreased by 2.79% and 3.25% compared to peritectic steel without Mg-Ti, respectively. Therefore, Mg-Ti treatment is an effective strategy to reduce peritectic transformation shrinkage, and thus alleviates the occurrence of surface cracks.

Key words： peritectic steel peritectic phase transition in situ observation Mg-Ti treatment
