Abstract

The mechanical properties of cold-worked reinforcement with 10.0 mm diameter of eutectoid steel after patenting and drawing in the short tempering under tension have been investigated. The features of changes for tensile strength σV, σV/ σ0,2 indicator, extension strain δ10, indentation hardness HIT, contact elastic modulus E*, steel in the processing temperature range 250-400°C and tensile force values from 20 to 60 kN were studied. The stress state of steel after treatment was estimated with X-ray diffraction analysis.

Keywords
