Abstract

A new crystallographic orientation relationship (OR) between MC (M, Ti, and Mo) and ferrite has been observed in microalloyed steel produced by new-generation thermo-mechanical processing (traditional TMCP involving ultra-fast cooling). The selected area electron diffraction (SAED) patterns present strong evidence for the new OR, that is (111)_MC//(110)_ferrite and 1¯10_MC//1¯10_ferrite, which hasn't been reported previously in MC/ferrite system. While the precipitates formed in the specimens with traditional TMCP obey the well-known Baker-Nutting (BN) and Nishiyama-Wassermann (NW) ORs. The coordinate transformation matrices for BN, NW and the new OR have also been calculated, which further confirms the uniqueness of the new OR.
