    摘要:

    采用X射線四環(huán)衍射及電子背散射衍射技術(shù)對(duì)Ni-9.3at%W(Ni9W)溫軋基帶表面進(jìn)行軋制織構(gòu)與再結(jié)晶織構(gòu)分析,研究了Ni9W合金基帶溫軋織構(gòu)的形成與轉(zhuǎn)變。結(jié)果表明,軋制過(guò)程采用溫軋的方法能有效提高Ni9W合金基帶軋制織構(gòu)中的S取向與C取向的含量,并且隨著變形量的增加 Ni9W合金基帶的形變織構(gòu)由黃銅型織構(gòu)向黃銅型和銅型的混合型織構(gòu)轉(zhuǎn)變,這有利于再結(jié)晶之后形成較強(qiáng)的立方織構(gòu)。

    Abstract:

    The deformation and recrystallization texture of the hot rolled Ni9W substrates (Ni-9.3at%W) were analyzed by four circle X-ray diffraction and EBSD measurements. The formation and transformation of hot rolling texture in Ni9W substrates were systematically studied. The results show that the hot rolling process can effectively increase the fractions of S- and C-type textures in the Ni9W tape. With the increase of the deformation reduction, the deformation texture of Ni9W tape is transformed from Brass to Brass and Copper hybrid texture, which is beneficial for the further formation of a strong cube texture after recrystallization annealing in these Ni9W substrates.
