Improving the Strength of Aluminum Alloys Produced by 3D Printing (Electric Arc Surfacing).

The cold strength and mechanical properties of AMg5 aluminum alloy produced by additive electric arc surfacing are considered. The mechanical properties of the 3D-printed alloy are worse than those of the rolled alloy. Quantum-mechanical calculations show that alloying with nanoparticles optimally improves the mechanical properties of aluminum alloys. Alloying with zirconium and tantalum or with titanium intermetallides is particularly effective. [ABSTRACT FROM AUTHOR]
