Special Issue Information

Dear Colleagues,

The development and performance optimization of high-performance alloys and steel have been a research focus for the past few decades, aiming to manufacture excellent industrial products. Numerous works and efforts have been made to elevate the performance of alloys and steel, including tuning design strategies, processing routes, and their application in the environment. However, the performance of the alloys and steel still does not meet the requirements of application fields, including extremely high/low-temperature conditions. Further improvement to the performance of alloys and steel is essential to elevate the service quality of industrial products. Therefore, this Special Issue aims to provide a broad platform to share the latest results in the development and performance optimization of high-performance alloys and steel. This includes fundamental questions regarding microstructure–property relationships, phase transformations, strain hardening, and fracture mechanisms. Submissions on topics related to the design, processing, testing, characterization, and applications of high-performance alloys and steel are welcome.

I am honored to serve as Guest Editor of the journal Materials for this Special Issue entitled “High-Performance Alloys and Steels: Design, Processing, and Applications”, providing academic exchange opportunities for colleagues from all over the world to support the research and development of high-performance alloys and steel.

The oxidation behaviors of varying Cr-alloyed automotive beam steels—0.015 wt.% Cr, 0.15 wt.% Cr, and 1 wt.% Cr—were investigated using isothermal oxidation experiments. The morphologies of the oxide scale were characterized, and the formation mechanisms were analyzed to understand the change in the oxidation kinetics of the investigated steels. The results show that a small amount of Cr, up to 0.15 wt.%, can reduce oxidation kinetics; the addition of Cr at 1 wt.% causes the oxidation rate to decline at a low isothermal temperature, but the hindrance effect expires when the oxidation temperature is above 1050 °C. The oxidation scale, including the inner FeO layer, the intermediate Fe3O4 layer, and the outer Fe2O3 layer, exhibits a morphological evolution from marble-like to pore-like, then whisker-like, flocculation-like, fine oxide grains, and finally coarse oxide grains. With increasing Cr addition, the thickness of the FeO layer decreases significantly, leading to a reduction in the total thickness of the oxidation scale. During the oxidation process of the investigated steel with 0.15 wt.% Cr, a Cr-rich layer and FeO-(Cr, Fe, Mn)3O4 eutectic form; meanwhile, FeO-(Cr, Fe)2O3 eutectic and Si-rich oxides, as well as a (Cr, Si)-rich layer, occur in the oxidation scale when 1 wt.% Cr is added to the steel. The occurrence of voids in the (Cr, Si)-rich layer is responsible for the increasing oxidation kinetics of the 1 wt.% Cr steel when the isothermal temperature is above 1050 °C, and the optimal Cr concentration in automotive beam steel is 0.15 wt.%, considering both oxidation resistance and cost.
