中文摘要:

塑造的费用的 electroformed 镍班机的二种类型被 elec-troforming 技术准备。X 光检查衍射(XRD ) ,传播电子显微镜学(TEM ) ,电子 backscattering 衍射(EBSD ) 技术和高分辨率电子显微镜学(HREM ) 被采用了调查在塑造的费用的 electroformed 镍班机形成的水晶缺点。没有任何添加剂,(100 ) 与成年方向平行的纤维质地在使用准备的 electroformed 镍存在的结果表演指导当前的 electroforming,并且(111 ) 纤维质地在与添加剂使用直接当前的 electro-forming 准备的 electroformed 镍存在。使用直接当前的 electroforming 准备的存款在长度在宽度和 170 m 与 30 m 的一种平均谷物尺寸拥有圆柱的谷物。与添加剂准备的存款由有谷物的结构大约 29 nm 缩放的一个殖民地组成,并且很多水晶背叛例如双胞胎,反相边界和叠的差错在 electroformed 镍被观察了。

英文摘要:

Two types of electroformed nickel liners of shaped charges were prepared by electroforming technique. X-ray diffraction (XRD), transmission electron microscopy (TEM), electron backscattering diffraction (EBSD) technique and high resolution electron microscopy (HREM) have been employed to investigate the crystal defects formed in electroformed nickel liners of shaped charges. The result shows that (100) fiber texture which is parallel to the grown direction exists in the electroformed nickel prepared by using direct current electroforming without any additives, and (111) fiber texture exists in the electroformed nickel prepared by using direct current electroforming with additives. The deposits prepared by using direct current electroforming possess columnar grain with an average grain size of 30 μm in width and 170 μm in length. The deposits prepared with additives are composed of a colony structures with grain size of about 29 nm, and a lot of crystal defects such as twins, antiphase boundaries and stacking faults have been observed in the electroformed nickel.
