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.

使用相关回归分析，研究了热机械轧制后的铁素体-珠光体和高强度（铁素体+贝氏体）钢的纵向和横向试样，其结构和化学成分对KC V冲击强度各向异性以及临界脆性温度差异的影响。证明了珠光体含量和硫化物夹杂物对铁素体-珠光体钢的纵向和横向试样的冲击强度各向异性和临界脆性温度差的显着影响。对于使用热机械轧制技术制备的高强度铁素体-贝氏体钢，碳和硫对横向试样脆化程度的影响被认为也取决于碳氮化钛和铝的含量₂ O ₃基氧化铝。
