Abstract

Abstract : A new method for pole figure measurement is described, entitled a dynamic segmented spiral scheme. This scheme provides a promising alternative to conventional methods of simultaneous texture and phase fraction measurement. Abstract : A new method for pole figure measurement is described, entitled a dynamic segmented spiral scheme. Compared with the schemes currently in use, the dynamically segmented spiral scheme is shown to have advantages in terms of evenness of pole figure coverage and phase fraction accuracy. The phase fraction accuracy is 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.
