IC—218合金的冷轧织构的退火织构

本文用极图和取向分布函数研究了ＩＣ－２１８合金（一种含共格γ相的Ｎｉ３Ａｌ（Ｂ）－Ｃｒ基合金）冷轧６０％后和１０００℃退火后的织构。实验结果表明，冷轧织构为｛１１０｝＜１１２＞＋｛１１２｝＜１１１＞，属纯铜式织构。在退火中，冷轧织构逐渐被消除，其中｛１１２｝＜１１１＞消失较快，代之以十分漫散的取向分布，并相继形成几种弱的再结晶织构：｛１，１０，７｝＜３１１＞，｛６１１｝＜０１１＞和｛１２３｝＜２１     

Al—Li薄板合金的织构梯度,平均织构和塑性各向异性

作者研究了再结晶ＡＡ８０９０和未再结晶ＡＡ８０９０及２０９０Ａｌ－Ｌｉ合金的织构随厚度的变化和薄板材的平均织构。使用退火状态下传统的ＡＡ２０２４合金作参照材。通过Ｘ射线衍射和中子衍射技术检查定量取向分布函数。使用Ｘ射线衍射仪，检查了从表面到板中心不同距离层的结构，得出织构梯度。通过中子衍射圆柱叠加层试样或者通过Ｘ射线技术计算各个层中获得的织构结果确定平均织构。表明一般轧制织构如「１１２」「１１１」

用三维取向分布函数对用新工艺研制的ＥＬＣ─ＢＨ钢板具有极高值的原因进行了织构分析，表明：①新工艺的核心是通过织构控制提供一个有利于｛１１１｝退火织构发展的冷轧母体；②新工艺得到的冷轧织构和退火织构与传统工艺相比明显不同，冷轧织构具有效强的｛１１１｝组分，退火织构的｛１１１｝组分密度提高且取向密度峰值对应的晶体学取向也由传统工艺的变为新工艺的。     

退火温度和时间对冷轧无取向硅钢组织与织构的影响

针对冷轧无取向硅钢退火工艺的特点,研究了退火温度和保温时间对成分为0.004%C、0.33%Si的冷轧无取向硅钢晶粒组织和织构演变的影响.结果表明:退火后,α线上{100}织构密度明显减弱,取向从{112}〈110〉向{111}〈112〉大量聚集;适当增加保温时间有助于提高{100}〈hkl〉织构,900℃、保温180 s,水冷得到的织构分布比较均匀,{001}面织构占有率比较高.     

N36锆合金管材的织构研究

利用X射线衍射测试技术,对N36锆合金成品管材的织构进行了测量。利用极图、织构取向因子,特别是采用三维晶体学取向分布函数等表征手段,系统分析了N36锆合金成品管材的织构特征。研究结果表明,N36锆合金成品管材的主要织构组分为基面型(0002)1120;管材径向上织构取向因子最大,大多数晶粒的[0002]基极集中在与管材的轴向垂直的ND-TD面上,并且偏离径向30°左右呈现典型双峰分布;除基面类型织构组分外,N36锆合金管材还存在一些相对强度比(0002)基面类型织构更高的锥面类型织构,而柱面类型织构较弱。
