Advances in Basic Research on Inclusion Induced Intragranular Acicular Ferrite and Nucleation Polymerization
It is a hot research topic in the field of iron and steel metallurgy to use oxide metallurgy technology to improve the toughness of welding heat affected zone of steel plate.From the two aspects of inclusion-induced intragranular acicular ferrite(IAF)nucleation and effective nucleation of composite inclusions,the inclusions that easily induce IAF,the crystallographic relationship between inclusions,the nucleation mechanism of IAF during the solidification of molten steel and the nucleation polymerization of complex inclusions were reviewed.It can provide ideas to further clarify the nucleation and growth evolution process of beneficial inclusions in oxide metallurgy.
