Anwendungen des TAP in der Materialphysik (Einweihung des TAP)
Nanostructured metallic materials – designing materials by visualization
of atoms using 3D atom probe
Prof. Dr. Kazuhiro Hono, National Institute of Materials Science, Tsukuba Japan |
A recent research trend in the metallurgical community is to refine the microstructural
scale from the conventional micron order to the nanoscale dimension.
When a crystal grain size becomes smaller than a few nanometers, where the
dislocation activity is lost and the ferromagnetic exchange coupling becomes
significant, various unique mechanical and magnetic properties appear. The characterization
of such nanocrystalline materials that are produced by various processing routes
can be performed most powerfully using the atom probe technique. In this talk, we
will give an overview on our recent research effort on the development of
nanocrystalline magnetic materials and nanocrystalline ultrahigh strength materials.
Based on 3DAP analysis results, we optimize the nanostructures so that improved
magnetic and mechanical properties can be achieved.
