摘要/Abstract

摘要： 利用电子背散射衍射(EBSD)技术研究了GH4169合金固溶和冷拉过程中的微观组织演变规律。结果表明,初始热轧棒材经固溶处理后,边部会出现晶粒异常长大现象,同时由于δ相阻碍晶粒长大的作用,正常晶粒和异常晶粒的尺寸差异不大。固溶处理后小角度晶界会向大角度转变,且边部出现了{111}<112>孪晶。冷拉过程中随着变形量的增大,不同区域的形变差异逐渐减小,当变形量达到30%时,不同区域的形变基本一致。在变形过程中随着位错的增殖,大角度晶界数量逐渐降低,小角度晶界数量逐渐增加。当变形量比较小时,边部的变形方式类似于轧制变形,因此会出现高斯织构和黄铜织构,随着变形量的增大,出现了典型的<111>丝织构,且织构强度也逐渐增加。

Abstract: Microstructure evolution low of GH4169 alloy during solution and cold drawing was studied by using electron backscattering diffraction (EBSD) technology. The results show that abnormal grain growth occurs at the edge of the initial hot rolled bar after solid solution treatment, and the difference in size between normal grain and abnormal grain is not obvious due to the pinning action of δ phase. After solution treatment, the small angle grain boundary changes to the large angle, and the {111}<112> twin appears at the edge. In the process of cold drawing, with the increase of deformation, the difference of deformation in different regions gradually decreases. When the deformation reaches 30%, the deformation in different regions is basically the same. With the proliferation of dislocations in the deformation process, the content of large angle grain boundary decreases gradually, and the content of small angle grain boundary increases gradually. When the deformation is relatively small, the edge deformation is similar to rolling deformation, so there will be Goss texture and brass texture. With the increase of deformation, the typical <111> silk texture appears, and the texture strength also increases gradually.
