Abstract

The rolling texture of a Pu-3.4 at. pct Ga alloy has been measured as a function of reduction. Both (111) and (200) pole figures were plotted from reflection data for specimens rolled 70, 80, 90, and 95 pct at room temperature. The texture develops smoothly and at all reductions bears a good resemblance to that of copper. At 95 pct reduction there is a strong <111> pole located 20 deg to either side of the rolling plane normal in the rolling direction, and the central pattern generally resembles an ellipse whose major axis lies in the cross direction. However, the spread of (111) pole intensity leads to interpretation of the pole figures in terms of a spread of orientations. Paired axes of rotation are used to describe this spread. In the early states of reduction the distribution of grain orientations can best be described by a rotation about the two strong <111> poles located to either side of the rolling plane normal in the rolling direction. As deformation proceeds two distinct orientations develop, related by rotations about these <111> poles, but the pole figure does not show all the associated <111> poles as expected. This can be explained by a spread of orientations, about a set of <110> poles, that decreases with deformation. At 95 pct reduction the missing <111> poles in the pole figure appear, though they are not as sharp as the others.
