The Fracture Toughness of TWIP Steels

Issue Date28-Sep-2016
AbstractTwinning-induced plasticity (TWIP) steels in the recent years have attracted intensive research interest due to their exceptional combination of strength and ductility. Despite their excellent tension property, some poor performances of this steel have been repeatedly reported, such as bad hole expansion, severe notch sensitivity, etc. In this report we claim that the fracture toughness as a property relates to the above mentioned performances. Investigation has been done focus on the fracture toughness of TWIP steel. The result suggests that the ductile steels, which show their high ductility during tension, are not so ductile in fact as we expected. It also reminds us to consider more when telling “good mechanical properties.
