Atomistic investigations of κ-carbide precipitation in austenitic Fe-Mn-Al-C lightweight steels and the effect of Mo addition

“…1(e) corresponded to those for κ-carbide precipitation in each steel. It is conceivable that the precipitation of nano-sized κ-carbide contributed to precipitation hardening, leading to the great increase in strength [1].…”

“…The characteristic of high specific strength in advanced steels has been traditionally achieved by increasing the strength, while many studies have recently tried to obtain specific strength by making the low density steels, the so-called lightweight steel [1][2][3]. The most widely investigated alloy design concept to obtain the low density has been to use light elements such as Al and Si with the Fe-Mn-C base alloy.…”

“…The most widely investigated alloy design concept to obtain the low density has been to use light elements such as Al and Si with the Fe-Mn-C base alloy. Depending on the chemistry, Fe-Mn-Al-C steels can be categorized by phase constituents as austenite, duplex and ferritic base steel [1], i.e., the higher Al content increases the stability of ferrite and κ-carbide, while the higher C and Mn content increases the stability of austenite.…”

Synthesis of Ultrastable Ag Nanoplates/Polyethylenimine–Reduced Graphene Oxide and Its Application as a Versatile Electrochemical Sensor

[10] Many colloidal Ag nanostructuresw ith well-defined morphologies had been synthesized in the absence of substrates, including cubes, [11] bars, [12] wires, [13] rods, [14] prisms [15] (or plates [16] ), bipyramids, [17] and dendritic nanostructures. [18] Among these nanostructures, two-dimensional Ag nanoplates (AgP)a re considered promising for applications in surface-enhanced Raman scattering (SERS), [19] sensors, [20] and catalysis.…”

Effects of Annealing Treatment Prior to Cold Rolling on Delayed Fracture Properties in Ferrite-Austenite Duplex Lightweight Steels

“…Al, a ferrite stabilizer, helps to form a duplex structure of ferrite and austenite at high temperatures. [9,10] It also promotes the precipitation of j-carbides (composition; (Fe,Mn) 3 -Al-C, perovskite structure) during cooling, and the amount of j-carbides varies with contents of Mn and C as well as Al. [11][12][13] Tensile properties of recently developed advanced high-strength steels (AHSSs) for automotive applications are superior to other conventional steels, but the active commercialization of these steels has been postponed because they are easily subjected to the cracking during formation or to the delayed fracture after formation.…”
