Atomsondentomographie

Tomographie in der Charakterisierung von Werkstoffen

Atomsondentomographie

Atomsondentomographie ist ein 3D-analytisches Verfahren mit nahezu atomarer Ortsauflösung und hoher chemischer Empfindlichkeit. Feldverdampfung einzelner Atome von einer nadelförmigen Probe, kombiniert mit Flugzeitspektrometrie und ortsauflösendem Detektor, erlaubt die Rekonstruktion der räumlichen Elementverteilung. In der Werkstoffwissenschaft wird sie zur Charakterisierung von Ausscheidungen, Segregationen, Grenzflächen und Legierungshomogenität eingesetzt.
