Analysis of Static and Cyclic Properties of 316L and AlSi10Mg in Conventional Casting and Additive Manufacturing.

The paper presents the original results of cyclic testing of materials that are identical in chemical composition but produced by two different technologies: conventional metallurgy and additive manufacturing. For the aluminium alloy AlSi10Mg and the austenitic steel 316L, tensile curves, tension-compression and torsion alternating fatigue curves are experimentally obtained and presented. The experimental results are compared for two fabrication technologies-conventional metallurgy and additive DLMS technology.

Strength and Cyclic Properties of Additive vs. Conventionally Produced Material AlSiMg.

Additive metals are practically identical in strength to the properties of conventionally produced materials. This article experimentally analyses strength properties and fatigue properties in the tensile-pressure mode for two different directions of 3D printing of AlSiMg material. The resulting fatigue parameters of the Basquin curve are confronted with a conventionally produced alloy of the same composition.
