Investigation of the local alloy composition by atom probe tomography (A04)

在SFB/TR 103的第三个资助阶段，项目A4的重点是应用原子探针断层扫描技术研究合金中相的局部组成。项目A4将使用新开发的方案，使用先进的电子显微镜技术生产具有目标缺陷的样品。项目A4测量以原子分辨率表征钴基和镍基合金蠕变变形过程中不同合金元素对特定缺陷的分布，并解释观察到的微观结构。

In the third funding phase of the SFB/TR 103, the project A4 focuses on the application of atomic probe tomography to study the local composition of phases in alloys. Project A4 will use the newly developed protocol to produce samples with targeted defects using advanced electron microscopic techniques. Project A4 Measurements to characterize with atomic resolution the distribution of different alloying elements to specific defects arising during creep deformation in Co-based and Ni-based alloys and to interpret the observed microstructure.
