    摘要:

    采用光學(xué)顯微鏡(OM)、X射線四環(huán)衍射(XRD)技術(shù)、電子背散射衍射(EBSD)技術(shù)分析研究了形變細化晶粒、潤滑軋制對Ni-9.3at.%W(Ni9.3W)合金基帶立方織構(gòu)形成的影響。結(jié)果表明,采用形變細化晶粒的方法能有效提高Ni9.3W合金基帶的立方織構(gòu)含量,并且隨著初始形變量的增加,晶粒細化程度越大,立方織構(gòu)含量越高,采用優(yōu)化的形變細化晶粒工藝使得Ni9.3W合金基帶立方織構(gòu)含量提高了9.8%。另外,增加形變細化晶粒后的軋制總變形量,立方織構(gòu)含量進一步提升了24.7%,根據(jù)以上結(jié)果,確定了初始坯錠制備階段的參數(shù)。在此基礎(chǔ)上,研究了軋制變形的潤滑與非潤滑對立方織構(gòu)形成的影響,相比非潤滑軋制而言,采用潤滑軋制,軋制織構(gòu)中獲得了較多的S取向與Copper取向,經(jīng)再結(jié)晶退火后,潤滑軋制基帶的立方織構(gòu)含量比非潤滑軋制基帶的立方織構(gòu)含量高9.6%,達到了86.7%(<15°),而且孿晶界數(shù)量、小角度晶界含量均要優(yōu)于非潤滑軋制,說明潤滑軋制對立方織構(gòu)形成有著積極的影響。

    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.
