If the volume fraction of IFP is larger than 60%, then the absorbed energy will go up to 150 J and more. The examination of optical microscopy and SEM exhibited that IFP consists of fine ferrite plates originating inside the initial austenite grains. These IFP forined by the so called "nucleating inclusions" as nuclei during the controlled cooling process after welding simulation. The nucleating inclusions are some fine and evenly distributed composite oxides with higher sulphur content, which result from the deoxidation by RE, Zr, Ti under a higher initial oxygen potential.
