200 kV Transmission electron microscope (TEM)

该提案概述了鲁尔大学波鸿材料研究所对新型透射电子显微镜的需求。我们申请更换一台使用了27年的200 kV透射电子显微镜，使用LaB6阴极，带有扫描和EDX单元。本提案的目的是获得资金，以便用新机器替换旧机器。新的TEM还必须能够在最大200 kV下运行。它应配备LaB6阴极，并应具有EDX单元和扫描模式。提案中概述的各种研究任务都需要该仪器。研究重点之一是单晶镍基和钴基高温合金的基元变形和组织演变过程。此外，形状记忆合金受到特别关注。双倾斜冷却保持器也适用于，它允许观察马氏体相变的显微组织特征在原位。

This proposal outlines the need for a new transmission electron microscope for the Institute for Materials of the Ruhr-Universität Bochum. We apply for the replacement of a 27 year old 200 kV transmission elecetron microscope with a LaB6 cathode, with a scanning and EDX unit. The objective of this proposal is to obtain funds which allow to replace this old machine by a new one. The new TEM must also be able to operate at a maximum of 200 kV. It should be equipped with a LaB6 cathode and should have an EDX unit and a scanning mode. The instrument is needed for various research tasks outlined in the proposal. One research focus is on elementary deformation and microstructural evolution processes in single crystal Ni and Co-base superalloys. Moreover, shape memory alloys receive special attention. A double-tilt cooling holder is also applied for, which allows to observe the microstructural features of martensitic transformations in situ.
