This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

A sintering‐resistant E‐Ni/m‐MgAlOx catalyst with exsolved Ni nanoparticles shows >1000 h stability in methane dry reforming, achieving cumulative greenhouse gas conversion above 20000 L·gcat−1 at 800 °C–900 °C. Abstract Sintering and carbon deposition are primary causes of deactivation in Ni‐based catalysts during methane dry reforming (MDR).

Radiation response of FeCrAl-coated Zircaloy-4
Abstract Coating the surface of Zircaloy-4 light water reactor fuel cladding tube is of considerable interest for enhancing its accident tolerance. In this study, thermal annealing of FeCrAl-coated Zircaloy-4 at 725 °C for 500 h, was used to induce interfacial reactions between Zircaloy-4 and FeCrAl.
