This booksummarizes the research results of carbide control in special steel from theauthor. It includes the evolution and control of carbide in special steel inthe process of electroslag remelting, rolling, and heat treatment, as well asthe effect of alloying treatment (rare earth, magnesium, nitrogen, titanium) asheterogeneous nucleating agent on carbide in special steel. It helps thereaders to understand formation mechanism and control technology of carbide inspecial steel deeply for improving the quality of special steel further. Thebook is useful as reference for researchers, practitioners, teachers, andengineering management team in fields of metallurgy and materials.
