Quantitative description of the morphologic texture in an Al-Li alloy

The aim of the present paper is to present a method for quantitative descri ption of the morphologic texture of grains in polycrystals. This method is based on computer-aided image analysis. It has been verified for studies of grain shape in commercial Al-Li-based alloy (8090). The results obtained f or this alloy show that even small changes in the alignment and elongation of grains can be detected. The quantified information on morphological text ure of grains can be further used to measure its contribution to anisotropy of the material in question. (C) 2001 Elsevier Science Inc.
