Application of electron backscattered diffraction and crystal orientation mapping to recrystallisation studies in high strength interstitial free steels

Electron backscattered diffraction (EBSD) has been demonstrated to be a val uable tool in gathering data to aid in the understanding of microstructural development in a variety of materials. A high strength interstitial free s teel has been studied using the capabilities of a modern EBSD system, parti cularly by use of the crystal orientation mapping facility. Grain boundary characteristics have been determined and used to develop an understanding o f the recrystallisation process. Little evidence in favour of the oriented growth theory has been found. It is proposed that the nucleation process du ring annealing is critical in controlling the fully annealed texture. MST/4 794.
