电解纯铜经88.7％冷轧后,所形成的轧制织构除稳定的(110)[112]舆(112)[111]外,还存在着一种(3,6,11)[533]织构。在较低温度下退火时,再结晶织构主要为(100)[001]、(358)[352]和舆(100)[001]成孪生取向的(122)[212]织构。随着退火温度的增加,(358)[352]织构逐渐减弱,立方织构(100)[001]则逐渐加强;当退火温度达到900℃时,开成了集中的(100)[001]织构。 冷轧铜板在退火的过程中,具有(100)[001]再结晶晶粒首先形成,然后普遍地发生同位再结晶。其中具有(100)[001]取向的晶粒,继续发生选择性的生长,最后形成了集中的立方织构。 本支中对轧制织构舆其再结晶织构取向间的关系也进行了分析,再结晶织构一般可认为是原有织构沿某一个[111]轴旋转45°,22°或38°的结果。同时,根据上述几何关系所绘出的理想极图舆实际测定的结果也是符合的。 试验结果指出,不同加热速度和不同加热程序对形成最终的再结晶织构,不发生显著的影响,而退火温度对再结晶织构的形成起着主要的作用。
In addition to the stable (110) [112] (112) [111], there is a (3,6,11) [533] Texture. The recrystallized textures are mainly (100) [001], (358) [352] and (100) [001] twinned (122) [212] textures when annealed at lower temperatures. With the increase of annealing temperature, the texture of (358) [352] gradually decreased and that of cubic texture (100) [001] increased gradually. When the annealing temperature reached 900 ℃, Texture. During annealing, the (100) [001] recrystallized grains are formed first and then recrystallized isotactically. The grains with (100) [001] orientation continue to grow selectively and finally form a concentrated cubic texture. The relationship between the recrystallized texture orientations of rolled textures has also been analyzed in this section, and the recrystallized textures can generally be considered as the original textures rotated 45 °, 22 ° or 38 ° along one of the [111] axes the result of. At the same time, according to the geometric relationship between the ideal pole map drawn by the actual determination of the results are consistent. The experimental results show that different heating rates and different heating procedures do not affect the formation of the final recrystallized texture significantly, whereas the annealing temperature plays a major role in the formation of recrystallized texture.
