Abstract
The paper presents a rapid texture measurement method and r-value prediction model for cold-rolled sheets using XRD nondestructive testing data. First the textural through-thickness inhomogeneity in two deep drawing steels, DC05 and DC06, was measured by XRD and described using the orientation distribution function (ODF), the results reveal that the textural inhomogeneity of cold-rolled sheet exhibits little through-thickness inhomogeneity. Then the experimentally measured r-values were compared with theoretical r-values calculated using the reaction stress model applied through the sheet thickness direction, a good match was found between r-values predicted by the reaction stress model based on the rapid texture measurement method at the sheet surface and experimental data. Finally the prospect for industrial application of this technique was discussed in detail. [doi:10.2320/matertrans.M2014276]
