Special Issue Information

Dear Colleagues,

After our successful first volume of the Special Issue “Plastic Deformation, Strengthening and Toughening of Advanced Metallic Materials”, we have decided to create a second volume to collect and publish state-of-the-art research in the field of plastic deformation, strengthening and toughening of metallic materials.

Metallic structure materials have been gaining widespread industrial applications, owing to their excellent properties. Strong metals are substantially desired in lightweight and energy-efficient industrial designs, such as in extensive applications of high-strength steels and aluminium (Al) alloys in automobiles, trains and planes. In most industrial alloy production and modern alloy design strategies, multiple obstacle families (for instance, solid solutions, particles and grain boundaries) and dislocations are employed to increase the strength. In recent years, numerous efforts have been contributed to processing high-strength metallic materials with good ductility or toughness. For such advanced alloys, the mechanisms of strengthening and toughening, as well as their plastic deformation mechanisms related dislocations evolutions, are still under debate.

In this Special Issue, we welcome the submission of original research articles, communications and reviews concerning the plastic deformation, strengthening and toughening of advanced metallic materials. Contributions demonstrating experiments, simulations and modelling related to the above subject are welcomed.

Dr. Fulin Jiang
Guest Editor

Abstract

The significant impact of Nb on ferrite transformation, both in terms of solute drag effect (SDE) and interphase precipitation, was investigated quantitatively. Ferrite transformation kinetics were characterized using thermal expansion experiments and theoretical calculations. The microstructures were characterized using high−temperature confocal laser scanning microscopy (CLSM), a field−emission scanning electron microscope (FESEM), and a transmission electron microscope (TEM). Under a higher driving force, interphase precipitations were observed in the sample with a higher Nb content. A three−dimensional (3D) reconstruction method was used to convert the two−dimensional (2D) image of interphase precipitation into a three−dimensional model for a more typical view. The SDE and interphase precipitation had opposite effects on the kinetics of ferrite transformation. A lower Nb content showed a strong contribution to the SDE, which delayed ferrite transformation. A higher concentration of Nb was expected to enhance the SDE, but the inhibition effect was eliminated by the interphase precipitation of NbC during interfacial migration. Both the experimental results and theoretical calculations confirmed this phenomenon. Full article
