Ductility of Nanostructured Bainite
Nanostructured bainite is a novel ultra-high-strength steel-concept under intensive current research, in which the optimization of its mechanical properties can only come from a clear understanding of the parameters that control its ductility. This work reviews first the nature of this composite-like material as a product of heat treatment conditions. Subsequently, the premises of ductility beh...
متن کاملRegeneration Technique for Welding Nanostructured Bainite
High-carbon steels which are transformed into extremely fine bainite plates embedded in a matrix of carbon-enriched austenite have recently been developed, and have found commercial application in the manufacture of engineering components. However, because of the large carbon concentration, they cannot be welded and this limits the scope for their exploitation. A method is reported here by whic...
متن کاملEffect of Isothermal Temperature on Growth Behavior of Nanostructured Bainite in Laser Cladded Coatings
The growth and propagation behavior of austenite-to-bainite isothermal transformation in laser-cladded, Si-rich, and Fe-based coatings is investigated. The crystallographic features, orientation relationship at different isothermal temperatures, and the morphology of the nanostructured bainite are determined. The Nishiyama-Wassermann type orientation relationship is observed at a high temperatu...
متن کاملHigh-Cycle, Push–Pull Fatigue Fracture Behavior of High-C, Si–Al-Rich Nanostructured Bainite Steel
The high-cycle, push-pull fatigue fracture behavior of high-C, Si-Al-rich nanostructured bainitic steel was studied through the measurement of fatigue limits, a morphology examination and phase composition analysis of the fatigue fracture surface, as well as fractography of the fatigue crack propagation. The results demonstrated that the push-pull fatigue limits at 10⁷ cycles were estimated as ...
متن کاملDevelopment of Hard Bainite
The T0 temperature in steel is defined as that at which ferrite and austenite of the same chemical composition have identical free energy. The T0 temperature is that below which it is possible for austenite to transform to ferrite of the same chemical composition after allowing for the strain energy due to the displacements associated with the transformation. Bainite is expected below the T0 te...
