Effect of Structural Factors on Difference in Structural Steel Longitudinal and Transverse Impact Specimen Embrittlement after Controlled Rolling and Thermomechanical Treatment

  • Published:
Metallurgist Aims and scope

Using correlation-regression analysis, the effects of structure and chemical composition on KCV impact strength anisotropy and difference in critical brittleness temperatures for longitudinal and transverse specimens of ferrite-pearlite and high-strength (ferrite + bainite) steels after thermomechanical rolling are studied. The significant effect of pearlite content and sulfide inclusions on impact strength anisotropy and difference in critical brittleness temperatures for longitudinal and transverse specimens of ferrite-pearlite steels is demonstrated. For high strength ferrite-bainite steels prepared using thermomechanical rolling technology the effect of carbon and sulfur on degree of embrittlement for transverse specimens is considered that also depends on the content of titanium carbonitride and Al2O3-based aluminum oxides.
