Abstract
Surface modification of alumina ceramic using a high energy density continuous wave laser beam is associated with the formation of highly faceted pyramidal surface grains. Recently, we developed a phenomenological model explaining the faceted morphology by a fiber texture with a strong (1-210) component. Based on high resolution electron back-scattered diffraction, the present work proposes a more precise model showing that faceting of surface grains is closely linked with the evolution of a strong (2-310) fiber texture.
