本文研究了纯铌在各种加工率下经中间及最终退火处理后,板材织构及制耳之间的关系。由X射线得织构极图表明冷轧织构为(001)[110]+(112)[1T0]+(111)[TT2]。再结晶后具有(111)[TT2]+(001)[110]+(111)[1T0]+(112)[1T0]等再结晶织构。实验结果表明深冲铌板在45°方向出现四个“制耳”主要由(001)[110]织构引起,而0°,45°方向出现的六个“制耳”是(111)[TT2]织构引起。此外还探讨了消除深冲“制耳”出现的可能途径。 In this paper, the relationship between the texture of the plate and the ear is studied after the intermediate niobium is annealed at various processing rates. The polarograph of X-ray diffraction shows that the cold-rolled texture is (001) [110] + (112) [1T0] + (111) [TT2]. After recrystallization, recrystallized texture such as (111) [TT2] + (001) [110] + (111) [1T0] + (112) [1T0] The experimental results show that the four “ear-making” appearing in 45 ° direction of deep-drawn niobium plate is mainly caused by the texture of (001) [110], and the six “ear-making” appearing in the direction of 0 ° and 45 ° are (111) TT2] texture. In addition, it explores the possible ways to eliminate the occurrence of deep-drawn “ears”.
