AA6061 Al alloy sheet was prepared by warm and hot asymmetric rolling at the temperature from 200 to 600°C. Pole figures of warm and hot asymmetric rolled AA6061 Al sheets were measured by X-ray diffractometer (XRD). Orientation distribution function (ODF) and the plastic strain ratio (R-value) were calculated. The calculated plastic strain ratio of starting sample was compared with those of different temperature warm and hot asymmetrically rolled samples. The plastic strain ratios of warm and hot asymmetrically rolled under different temperature and subsequently heat treated AA6061 Al sheets were shown higher than that of starting sample, but ΔRvalues expect 600°C were lower than that of starting sample.
