【摘要】：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。
[Abstract]:The orientation and texture formation of Ni-W alloy base band with W (atomic fraction) of 5%, 7% and 9.3% respectively in cold rolling and recrystallization heat treatment are systematically studied by X ray diffraction and electron backscatter diffraction. With the increase of W content, the increment of the orientation content of S and Copper in the base band of Ni-W alloy gradually decreases, while the increment of Brass orientation content increases, and the final low W alloy obtains the Copper type rolling texture, while the high W alloy obtains the Brass type rolling texture. During the recrystallization heat treatment, the low W alloy cubic grain nucleation is early and rapidly grows, and in the recrystallization process. The cubic texture is easily obtained by swallowing other orientations, and the cubic grain of high W alloy is nucleated and grown together with other orientated grains, and the growth rate is less than that of other orientated grains, finally forming a random orientation.
