Scientists Reveal Niobium's Dual Role in Stabilizing High-Silicon Austenitic Steel for Lead-Cooled Fast Reactors
Scientists from the Institute of Metal Research of the Chinese Academy of Sciences, in collaboration with researchers from The Hong Kong Polytechnic University, have clarified the dual regulatory role of niobium (Nb) in the microstructural stability of high-silicon austenitic stainless steel, offering a new strategy to suppress austenite decomposition during long-term service at elevated temperatures.
