    Abstract:

    Influence of deformation refinement grain and lubrication rolling on the cube texture formation in Ni-9.3at.%W(Ni9.3W) alloy substrate was analysised by optical microscope(OM), X-ray diffraction(XRD) and electron backscattered diffraction(EBSD) technique. The results show that the method of deformation refinement grain can effectively improve the cube texture content in Ni9.3W alloy substrate. The grains are finer according to the increase of deformation reduction, which results in obtaining a higher cube texture content in annealed substrate.The cube texture content by the optimized deformation refinement grain increases 9.8% higher than that without deformation refinement grain in Ni9.3W alloy substrate. Besides, cube texture content increases further 24.7% by adding total rolling deformation after deformation refinement grain. According to these results, the parameters for preparation of the initial ingot are determined. On the basis of it, the influence of lubrication rolling on cube texture formation is also studied by compared with that without lubrication rolling. Lubrication rolling is able to get more S and Copper orientation in rolling textures. After recrystallization annealing, cube texture content with lubrication rolling reaches 86.7% (<15°), which is 9.6% higher than that without lubrication rolling. In addition, the twin boundary quantity and low angle grain boundary content by lubrication rolling is superior to that without lubrication rolling, which illustrates that lubrication rolling has a significant effect on the cube texture formation.
