Qualitative Analysis of the Large Plastic Deformed Al-Mg Alloy Probe Using Atomic Force Microscopy

Résumé

AFM is a method used for qualitative investigations of the two probes of Al-Mg alloy. The probes represent two states of the material: 1) initial state, 2) deformed under progressive shearing and cumulating a large strain rate. In the last case, the material is nanostructured, that means the grain size is diminish. The paper deals with the measurement of the grain size, roughness and anisotropy of the material by means of the Fourier analysis.
