中文摘要:
      采用光学显微镜(OM)、X射线四环衍射(XRD)技术、电子背散射衍射(EBSD)技术分析研究了形变细化晶粒、润滑轧制对Ni-9.3at.%W(Ni9.3W)合金基带立方织构形成的影响。结果表明,采用形变细化晶粒的方法能有效提高Ni9.3W合金基带的立方织构含量,并且随着初始形变量的增加,晶粒细化程度越大,立方织构含量越高,采用优化的形变细化晶粒工艺使得Ni9.3W合金基带立方织构含量提高了9.8%。另外,增加形变细化晶粒后的轧制总变形量,立方织构含量进一步提升了24.7%,根据以上结果,确定了初始坯锭制备阶段的参数。在此基础上,研究了轧制变形的润滑与非润滑对立方织构形成的影响,相比非润滑轧制而言,采用润滑轧制,轧制织构中获得了较多的S取向与Copper取向,经再结晶退火后,润滑轧制基带的立方织构含量比非润滑轧制基带的立方织构含量高9.6%,达到了86.7%(<15°),而且孪晶界数量、小角度晶界含量均要优于非润滑轧制,说明润滑轧制对立方织构形成有着积极的影响。

英文摘要:
      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.
