Comparison of Damage Evolution in Different Steels by Means of 3D X Ray Tomography Conferences

abstract

• In this paper, the damage behavior of three different steels is studied by the means of 3D X ray tomography in tension: a Fe22Mn0.6C austenitic TWIP steel, a 316 L austenitic stainless steel, and an interstitial‐free (IF) ferritic one. The comparison gives a better insight into the damage of the twinning‐induced plasticity steel (Fe22Mn0.6C), which is a promising one due its very high mechanical properties. It is shown that the damage process of this type of steel involves not only an important nucleation of small voids but also a large growth of the biggest cavities. This last conclusion is true even if a constant macroscopical triaxiality is observed.
