Macrostructure and Mechanical Properties of Al – Si, Al – Mg – Si, and Al – Mg – Mn Aluminum Alloys Produced by Electric Arc Additive Growth

Аннотация

The macrostructure and mechanical properties of clad metal produced by electric arc additive growth using wires of aluminum alloys of three alloying systems (Al – Si, Al – Mg – Si, and Al – Mg – Mn) are studied. The distribution of the pores is assessed, the porosity and the microhardness are evaluated. The anisotropy of the mechanical properties determined in some specimens is explained.
