Effect of processing parameters including cold work and grain size on texture development in copper and 68:32 a-brass thin sheets is investigated. The preferred orientation of grains (texture) is represented quantitatively by the orientation distribution function (ODF) as derived either by X-ray diffraction or by ultrasonic velocity measurements. The texture-induced elastic moduli are derived in the sheet plane at various orientations to the rolling direction. The predicted values of elastic moduli are compared with the mechanically measured ones. An attempt is made to empirically correlate ODF coefficients to the mechanically measured elastic modulus and plastic strain ratio (r-value). The sources of discrepancies such as the limitations of the measuring techniques and the models applied are discussed. |
