The Influence of Microstructural Features and Mechanical Properties on the Cold Formability of Ferritic Steel Sheets

摘要: In the present study, formability of cold rolled and annealed steel sheets having carbon equivalent values in range 0.028 to 0.098 wt% were investigated. The sheet lowest was a titanium-stabilized interstitial free steel, which established highest strain hardening exponent, anisotropy coefficient higher Forming Limit Diagram (FLD). Since plain intercept (FLD 0 ) is most critical limit on FLD, empirical equations derived between FLD microstructural features mechanical properties. As feature grain size as property gave reliable correlations.
