温轧对Ni9W合金基带织构形成的影响

Effects of Hot Rolling on the Texture Formation in Ni9W Substrates

采用X射线四环衍射及电子背散射衍射技术对Ni-9.3at%W(Ni9W)温轧基带表面进行轧制织构与再结晶织构分析,研究了Ni9W合金基带温轧织构的形成与转变。结果表明,轧制过程采用温轧的方法能有效提高Ni9W合金基带轧制织构中的S取向与C取向的含量,并且随着变形量的增加Ni9W合金基带的形变织构由黄铜型织构向黄铜型和铜型的混合型织构转变,这有利于再结晶之后形成较强的立方织构。

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.
