Investigation of Acicular Ferrite Structure and Properties of C-Mn-Al-Ti-N Steels
Low carbon-manganese wrought steels with addition of Ti-Al-N have been treated in order to obtain acicular ferrite structure. The microstructure of fine acicular ferrite nucleated intragranularly on Ti(C,N)+AlN and Ti(C,N)+AlN+MeS inclusions has showed high strength and toughness at low temperatures.
