The effects of RE on the inclusions and the mechanical properties of 10PCuRE steel were studied. The results show that the morphologies and sizes of inclusions in 10PCuRE steel are changed, and RE played a very good role of modifying inclusions. Fracture is changed from cleavage to ductile fracture by adding RE to 10PCuRE steel. And the mechanical properties of 10PCuRE are improved. In comparison with 10PCuRE steel without RE, the transverse impact toughness of 10PCuRE steel with RE is increased 30.15% at -20°C, and the tensile strength and reduction of area have been improved 27.14%, 8.9%, respectively.

Structure Properties

Among all minerals, iron is one of the elements identified early by human beings to take advantage of and be used. The role of iron in human life is so great that it made an era in the ages of humanity. Pure iron has a shiny grayish-silver color, but after combining with oxygen and water it can make a colorful set of materials with divergent properties. This diversity sometimes appears ambiguous but provides variety of applications. In fact, iron can come in different forms: zero-valent iron (pure iron), iron oxides, iron hydroxides, and iron oxide hydroxides. By taking these divergent materials into the nano realm, new properties are exhibited, providing us with even more applications. This review deals with iron as a magic element in the nano realm and provides comprehensive data about its structure, properties, synthesis techniques, and applications of various forms of iron-based nanostructures in the science, medicine, and technology sectors.
