Crystal Orientation of Intragranular Ferrite from B1 Type Compounds in Steels

摘要

The exact mechanism of intragranular ferrite nucleation has not been clarified yet, although some possibilities such as lattice matching, chemical reaction and localized stress have been suggested1). Especially, B1 type compound has interested many researchers because of its low mismatch with ferrite and Baker-Nutting orientation relationship ((001)α//(001)B1, [110]α//[100]B1) is the most preferred way to explain ferrite nucleation from B1 type compounds. However, in spite of the similar misfit of TiO, TiN
