200 kV Transmission electron microscope (TEM)

该提案概述了波鸿鲁尔大学材料研究所需要一种新的透射式电子显微镜。我们申请用LaB6阴极取代已有27年历史的200千伏电子显微镜，并配备扫描和能谱装置。这项提议的目的是获得资金，以便用一台新机器取代这台旧机器。新的瞬变电磁还必须能够在最大200千伏的电压下运行。它应配备LaB6阴极，并应具有EDX单元和扫描模式。该仪器是提案中概述的各种研究任务所必需的。其中一个研究重点是单晶镍基和钴基高温合金的元素变形和组织演变过程。此外，形状记忆合金受到了特别的关注。还采用了双倾斜冷却夹持器，可以原位观察马氏体相变的显微组织特征。

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.
