Summary: | ▶ Three steels with same thickness, yield strength and similar plastic tensile properties were studied. ▶ They showed very different forming and fracture behaviour depending on the strain path. ▶ This was due to the differences in microstructure between these three steels. ▶ The second phase deformation was the dominant factor to get the ductile or rapid post uniform deformation failure.
The fracture behaviour of two Advanced-High-Strength-Steels (AHSS) of similar yield strength can have a sudden change from ductile to rapid post uniform deformation failure depending on the strain-path. Microstructure analysis indicates that the different failure modes are due to a change in the ability of the second phase to deform. |
