An anisotropy of the tensile mechanical properties of a billet of austenitic Fe-18Cr-9Ni-0.08C steel produced by the method of wire-feed electron-beam printing was investigated. It was experimentally shown that after additive growth, samples of austenitic steel, which were cut from different parts of the steel billet and differently oriented with respect to the direction of growth, possess the significant anisotropy of mechanical properties under uniaxial tension.

The coarse-grained (CG) materials typically exhibit excellent ductility but poor strength. By contrast, the ultrafine-grained (UFG) or nanocrystalline (NC) materials typically exhibit high strength but poor ductility. However, in this work, the gradient-grained structure materials have superior combination of high strength and good ductility.
