    Comparison of fatigue behaviour of AlSi10Mg CT samples prepared by casting and by additive technologies

  • Original language description

    The achieved mechanical properties influence the usability of parts prepared by additive technologies. Investigating the mechanical properties of parts and materials for additive technologies is currently one of the most up-to date topics. In this work, an electromechanical testing method is chosen, which analyzes the formation and propagation of a crack in the aluminum alloy AlSi10Mg prepared from metal powder by the additive technology DMLS (direct metal laser sintering). Testing is performed on CT (compact tension) samples according to ČSN ISO 12108 on test machine Instron Electropuls 10000, and the results are compared with values obtained by testing samples made by gravity casting from an aluminum alloy of comparable composition. 3D printing of CT samples is performed in various topologies to verify the dependence of fatigue behavior on the printing topology with the aim of applicability in determining suitable printing topologies depending on the shape of the part and the direction of stress in the practical use of parts. The research monitors the dependence of the crack formation time and its propagation speed on the print orientation of the test specimen. The results of testing determine the appropriate printing topology in order to find the ideal position of a sample during printing and assess the possible use of this 3D printed material for cyclic loaded parts.
