Ferrite Nucleation

The nucleation of intragranular acicular ferrite in the welding heat-affected zone of Ti-bearing high strength low alloy steel was investigated by means of electron microscopy. It was found that intragranular acicular ferrite nucleation sites under different welding heat inputs (4.3kJ/mm and 10.0kJ/mm) are titanium complex oxides on which manganese (Mn) sulfides are precipitated. The complex compound is a Si and Mn-enriched oxide. Analysis of the oxide by means of enenrgy dispersive X-ray spectrum indicated that the oxide has higher absorption ability of Si than that of Mn.
