1. Introduce – Cerium is the most abundant rare earth element in the lanthanide series and is a metal with atomic number 58. – It has a silvery-white luster and is relatively reactive, oxidizing fairly quickly in air. – From a metallurgical perspective, cerium goes beyond being a simple additive; it acts as a key “vitamin” for controlling the microstructure and enhancing the performance of steel and non-ferrous alloys. – In particular, based on its strong chemical affinity with oxygen and sulfur, it is an essential alloying element for controlling impurities within meta...
