Formability of Dual-Phase Steels

The mechanical behavior of dual-phase steels depends on a broad range of metallurgical phenomena. The initial hardening reflects the volume fraction of the martensitic phase via a back stress, but this also depends on the local strength of the martensite. Formability is related not only to strain hardening and other continuum properties such as normal plastic anisotropy, but may also be influenced by fracture phenomena associated with discrete …
