Project B06 uses atomic-resolution scanning transmission electron microscopy and related spectroscopy methods to investigate the atomic structure and chemical composition of grain boundaries in pure Ni and Ni-X (X= Cu, Au, Nb) alloys. A major focus of the experiments is the detection of temperature-dependent, mechanically or chemically induced phase transformations of grain boundary defect phases. The influence of the grain boundary defect phase on the transmission of dislocations and thus on the plasticity is investigated with in-situ electron microscopy using novel, micro-additively manufactured mechanical sample carriers.

B06项目采用原子分辨扫描透射电镜及相关光谱学方法研究纯Ni和Ni-X （X= Cu, Au, Nb）合金的原子结构和晶界化学组成。实验的一个主要焦点是检测温度依赖，机械或化学诱导晶界缺陷相的相变。采用新型微增材制造的机械样品载体，利用原位电子显微镜研究了晶界缺陷相对位错传递和塑性的影响。
