| 1 | Microstructure and texture of electroformed copper liners of shaped charges显示文摘The microstructures of copper liners of shaped charges prepared by electroforming technique were investigated by transmission electron microscopy (TEM). Meanwhile, the orientations distributing of thegrains in the electroformed copper liners of shaped charges was examined by the electron backscattering Kikuchi pattern (EBSP) technique. TEM observations have revealed that these electroformed copper liners of shaped charges have the grain size of about 1-3 m and the grains have a preferential orientation distribution along the growth direction.EBSP analysis has demonstrated that the as-formed copper liners of shaped charges exhibit a micro-texture, i.e. one type of fiber texture, and the preferred growth direction is normal to the surface of the liners. | WenhuaiTian HongyeGao AilingFan XiaoouShan QiSun | 2002 | Journal of University of Science and Technology Beijing2002，9，4： | 2 |
| 2 | Effect of current density on the morphology of Zn electrodeposits显示文摘The effect of current density on the morphology of Zn electrodeposits prepared by a flow-channel cell was investigated by scanning electron microscopy (SEM). It was found that the morphology of Zn electrodeposits evolves from thin-layered hexagonal η-phase crystals to pyramidal η-phase particles with increasing the current density. The morphological evolution at various flow rates was also examined and the results show that the morphological evolution at a lower flow rate is more remarkable than that at a higher flow rate with increasing the current density. To reveal the mechanism of the morphological evolution in detail, the atomic configuration on both (0001)η and { 1100 }η planes under different current densities was investigated, it was noted that a specify current density could provide a good condition for the layered epitaxial growth of hexagonal η-phase. | AilingFan WenhuaiTian M.Kurosaki | 2004 | Journal of University of Science and Technology Beijing2004，11，6： | 0 |
