The exceptionally good structural work-hardening of last generation aluminium alloys and steels find their origin in nanometric precipitation. To understand the macroscopic mechanical properties of these alloys, fine analysis are undergone, at a scale that requires up-to-date characterization techniques.
These studies not only allow to determine the the size, volume fracion of nanoprecipitates, distances between them, and the orientation relationship between the precipitates and the matrix, but also the stresses generated by the precipitates in the matrix, as well as their resistance.
