Investigation of mechanical properties of the AA5356 walls produced by electron-beam additive process

In this study, thick-wall products made of aluminum-magnesium alloy 5356 were produced by wire-feed electron beam additive technology. The wall-shaped samples were printed using two different types of a printing process. A three-point bending test method was chosen to characterize their mechanical properties. Analysis of samples after three-point bending test showed the distribution of cracks along the direction of applied loading. A decrease in porosity is observed with the increase in the amount of heat input. It is shown that high strength properties are typical for samples printed with a higher value of heat input.
