Electron backscattered diffraction analysis (ebsd) analysis of thermomechanically processing metals and alloys

This project will use a recently acquired field emission gun (FEG) SEM equipped with EBSD analysis equipment. Recent advances in the EBSD technique, that have significantly improved angular resolution, in conjunction with a FEGSEM have made it a feasible alternative to the TEM as a tool for quantifying deformation microstructure. Parameters such as sub-grain orientation and size, misorientation distribution, misorientation gradients, and orientations and growth rates of recrystallising grains can now be routinely quantified over a statistically significant sample size. Such variables form the basis of the newly developing physically-based equations that describe microstructure evolution in hot-worked metals. Therefore this project will examine the applicability of the EBSD technique for a wide range of thermomechanical processed alloys including aluminium, IF steel and Ti-based alloys.
