Abstract
Methods for determining a recovery state of a metal alloy are disclosed herein. In one example, a fluctuation in a crystallographic grain orientation of the metal alloy is determined by utilizing electron backscatter diffraction (EBSD) data of the metal alloy. A processor of an electron backscatter diffraction machine utilizes a local orientation deviation quantifier to correlate the fluctuation in the crystallographic grain orientation of the metal alloy with a plastic strain recovery of the metal alloy. Other examples of the method are also disclosed herein.
