Anisotropy of the Mechanical Properties of Thermally Hardened A500s Reinforcement

  • Ya. Z. Blikhars’kyiEmail author

We study the distribution of microhardness of a rebar 20 mm in diameter made of A500S steel in the radial direction and determine the thickness of thermally hardened layer. To estimate the anisotropy of strength and plasticity characteristics over the thickness of the rebar, we use tubular specimens whose working part contains either solely the hardened layer of the rebar or only the core material. We also construct the engineering and true stress-strain diagrams in tension. It is demonstrated that the mechanical characteristics of the material of the surface layer of rebar strongly differ from the characteristics of its core material.
