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.

在SFB/TR103的第三个资助阶段，A4项目侧重于应用原子探测层析技术来研究合金中相的局部成分。项目A4将使用新开发的协议，使用先进的电子显微镜技术生产具有靶向缺陷的样品。项目A4测量，以原子分辨率表征不同合金元素在钴基合金和镍基合金蠕变变形过程中产生的特定缺陷的分布，并解释观察到的微观结构。
