A method for pole figure measurements via a dynamic segmented spiral scheme



Surya Chandramouleeswaran, Adam Creuziger, Kip Findley


A new method for pole figure measurement is described, titled a dynamic segmented spiral scheme. Compared to schemes currently in use, the dynamically segmented spiral scheme was shown to have advantages in term of evenness of pole figure coverage, time per measurement, and phase fraction accuracy. The phase fraction accuracy was shown to be robust for a variety of texture components commonly encountered in steels and for texture sharpness exceeding what is commonly encountered for rolled sheet steels. This scheme provides a promising alternative to conventional methods of simultaneous texture and phase fraction measurement.
