Abstract

The article considers the results of studying the influence of the microstructural parameters of Charpy specimens with a sharp stress concentrator and Mesnager specimens with a circular stress concentrator from rolled products of various thicknesses on their impact strength at temperatures from 0 to –80°C with an increment step of 20°C. The used roll products were made from low-carbon microalloyed steel at JSC “Vyksa Steel Works”. The tests were conducted using optical and scanning electron microscopy. It is shown that the thinner metal pieces (6 and 8 mm) have the same chemical composition and are treated in the same thermomechanical modes as their thicker counterparts but have higher strength properties (by 10 MPa on average for temporary resistance and by 30 MPa for yield strength) and a viscosity margin at negative temperatures at close grain score values and average grain size corresponding to numbers 10–11 according to GOST 5639. The lowest level of cold resistance is shown by the metal pieces with a thickness of 12 mm, and their brittle transition temperature is -50°C. The structure of the rolled products of various thicknesses exhibits variations in grain size. The thinner rolled products contain smaller grains corresponding to number 14. The thicker rolled products contain larger grains corresponding to number 8. The electron microscopic examination by the Electron Backscatter Diffraction (EBSD) technique helps find out that the rolled products of 6 and 8 mm in thickness contain more high-angle boundaries, which are barriers for brittle cracking. The constructed orientation maps of microstructure reveal the presence of pronounced strain texture corresponding to orientations 〈110〉 || RD (rolling direction) and (〈113〉…〈112〉) || RD for the rolled products with a thickness of 6 mm.
