研究了(110)[001]、(111)[112]和(320)[001]取向的钨和铌单晶体经70％,80％和85％轧制后的冷轧及再结晶织构。得到了与钼和铁硅单晶体完全一致的结果。从再结晶织构和冷轧织构之间的联系,以及形变带之间的过渡区域在再结晶过程中的作用出发,讨论了再结晶织构的形成,认为再结晶晶核的形成是一个同位再结晶的过程,而再结晶织构形成的普遍规律,可以概括地称为同位再结晶——择优长大。
The cold-rolling and recrystallization textures, after reductions of 70, 80 and 85 per-cent, of tungsten and niobium single crystals with (110) [001], (111) [112] and (320)[001] orientations have been investigated. The results are the same as those obtainedin Mo and Fe-Si single crystals. From the relationships between the recrystallization androlling textures, and the part played by the regions between slip bands in the recrystal-lization process, the mechanism of formation of the recrystallization textures has been dis-cussed. It is believed that the nucleation is a process of recrystallization in situ, andthe formation of recrystallization textures may be described generally as a process of re-crystallization in situ and preferred growth.
