The uncompleted pole figures of W80Cu20 and W80Cu20 alloy sheets after multi-pass hot-rolling were measured by XRD texture instrument at angles from 0° to 90°. And their texture evolution law was analyzed by the orientation distribution functions (ODF). The results indicate that W80Cu20 alloy before rolling has no texture, because its orientation density value is closely to 1 with poor and non-obvious texture. But hot-rolled W80Cu20 alloy sheets have obvious rolling texture and preferred orientation with greater orientation density. As well, the sheets have their stable texture components: Brass type texture {110}<112>, Copper type texture{211}<111> and rotating cubic texture {200}<011>
