Tensile tests are performed with specimens, which possess a comparable microstructure, a constant thickness/width and width/length ratio whereas the thickness varies from 10 to 250 m. Results show a transition from ductile to a macroscopically “brittle” behavior in the range of about 20 m.en620 - Ingenieurwissenschaften und Maschinenbau04B - Beitrag Konferenzschrift89–96
