In particular, during torsion tests a video system for analyzing strain fields on the surface of the sample Vic-3D was used. The dependences of elastic and plastic characteristics are shown depending on the orientation of the samples with respect to the direction of growth. The values of the anisotropy coefficient of mechanical properties in tension and torsion are compared. It is shown that under torsion the anisotropy coefficient of properties has larger values than under tension. © 2023 The Authors. Published by ELSEVIER B.V.

Introduction Currently additive technologies are being actively introduced into production processes which have a number of advantages over traditional technologies for manufacturing complex-shaped products (Igesenov et al., 2018). One of the types of additive technologies is selective laser melting of metal powders (Dinin et al., 2017). At present this 16th International Conference on Mechanics, Resource and Diagnostics of Materials and Structures (MRDMS 2022) Tensile and torsion tests of cylindrical specimens of aluminum alloy ASP35 obtained by the SLM method Ilinykh Artem V., Pankov Alexandr M. *, Strungar Elena M., Tretyakova Tatyana V.
