采用压延辅助双轴织构基板制备路线,结合X射线衍射和电子背散射衍射技术,系统研究了W量(原子分数)分别为5%、7%和9.3%的Ni-W合金基带在冷轧形变和再结晶热处理过程中的取向及织构形成的变化规律。研究发现,在冷轧形变过程中,随着W含量的增加,Ni-W合金基带中S和Copper取向含量的增量逐渐降低,而Brass取向含量的增量则呈现上升趋势,最终低W合金获得Copper型轧制织构,而高W合金获得Brass型轧制织构。在再结晶热处理过程中,低W合金立方晶粒形核较早并迅速长大,吞并其它取向,容易获得立方织构;高W合金的立方取向晶粒则和其它取向晶粒一同形核和长大,且长大速度不及其它取向晶粒,最后形成杂乱取向。
The preparation route of the biaxially-oriented textured substrate by calendering was studied. The effects of the amount of W (atomic fraction) of 5%, 7% and 9.3% Ni-W alloy matrix on the cold rolling Deformation and recrystallization heat treatment during the orientation and texture changes in the formation. The results show that with the increase of W content, the increment of orientation of S and Cu in the base band of Ni-W alloy gradually decreases and the increase of the content of Brass orientation increases with the increase of W content. The final low W alloy Copper-type rolled texture was obtained, while high-W alloy was obtained Brass-type rolled texture. During the recrystallization heat treatment, the cubic grains of low-W alloy nucleate earlier and grow rapidly, swallowing other orientations and easily obtaining cubic texture. The cubic grains of high-W alloy nucleate with other oriented grains and Grow up, and grow faster than other grain orientation, the final formation of messy orientation.
