Abstract

In this work, high-resolution transmission electron microscopy was used to study features of the structure of the age-hardenable aluminum alloy AlSi10MgCu, produced by selective laser melting, after quenching and artificial aging. Some aspects of the application of Fourier transform to determine the crystal structure of precipitations are described. The identification of crystalline structure of fine particles formed in this alloy during aging has been carried out, and their orientation relations with the matrix have been established.
