“…It is worth noticing that the number of voids at fracture is, in this case, very low considering all other type of ductile material at fracture. [5,7,9] 3.3. Void Growth X ray tomography permits to decorrelate void nucleation from void growth.…”

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.

“…[10][11][12][13] Canadinc et al [9] showed a drastic increase in critical resolved shear stress and strain hardening coefficients in N-alloyed Hadfield steel. They attributed the additional hardening contributions to the coexisting deformation twins and nitride precipitates, both acting as strong obstacles against dislocation motion.…”

“…The higher levels are explained with the high density of dislocation walls, forming barriers to dislocation glide. Abbasi et al [12,13] demonstrated that, in Al-modified Hadfield steel, the increase in yield strength goes along with a decrease of the total elongation, the ultimate tensile strength, and work hardening capacity. They report that Al in Hadfield steel can alter the main deformation mechanism.…”

Two modified X120Mn12 Hadfield steels, differing in the amount of the alloying elements Al and N, are analyzed with respect to AlN precipitation and its effects on ductility. Charpy impact tests are performed, demonstrating the loss of ductility in the one grade containing a high density of AlN precipitates. The characterization of the precipitates is carried out by high-resolution scanning electron microscopy (HRSEM). Depending on chemical composition, primary and secondary AlN precipitates are detected on prior austenite grain boundaries and within the bulk volume. The experimental observations are confirmed by thermokinetic simulations, using the software package MatCalc (

“…Heat treatments at 1000 to 1100°C for suitable times according to thickness of components, and consequently water quenching, dissolve the brittle phases and prevent the reformation of carbides during the cooling period and produce austenitic microstructure. Care should be observed to prevent local melting due to carbon segregation (Abbasi et al, 2009;Bhero et al, 2013). However, the solution treatment at high temperatures may lead to grain growth.…”

In this paper, the effect of boron content in chemical composition of steel on improvement of microstructure and mechanical properties of manganese steels was investigated. The microstructure, by optical, SEM and FESEM microscopy, was investigated. In addition, mechanical tests such as tensile test, hardness and impact tests were performed on the samples. Microscopic test results show that the presence of 0.007% of boron consistently prevents formation of carbides in grain boundaries and also reduces the carbide sizes and improve uniform distribution. In presence of boron, annealing solution heat treatment, improve the morphology of carbides and modified it to spherical shape. The manganese steels by addition of boron alloy element and solution heat treatment, have higher hardness, impact energy and tensile strength.
