Full Description
Exploration into the latest research and developments in material corrosion resistance and related technologies
Steel Corrosion and Metallurgical Factors: Laws and Mechanisms offers an in-depth exploration of the latest research on modulating metallurgical factors in various types of steel materials to enhance their corrosion resistance. The book covers a diverse range of materials, including low-alloy steels, stainless steels, ductile iron, rebar, and pipeline steel, and outlines the application of corrosion big data technology and artificial intelligence in the revealing of material corrosion mechanisms.
The book discusses how typical metallurgical factors such as inclusion control, alloying control, and heat treatment control influence the corrosion resistance of stainless or low alloy steels and provides theoretical guidance for corrosion-resistant steel smelting technologies (e.g., inclusions regulation, alloy modulation, and rolling processes) by investigating the laws and mechanisms underlying the influence of various metallurgical factors on the corrosion resistance of steel.
Steel Corrosion and Metallurgical Factors includes information on:
Micro- chemical-electrochemical theory of corrosion initiation induced by various typical types of inclusions in stainless and low alloy steels
Influence of elements such as Ca, Sb, Cu, and Cr on the resistance of low-alloy steels to microbial and marine atmospheric corrosion
Coupled mechanism of microstructure and inclusions in corrosion initiation in steel
Behavior and mechanism of stress corrosion and hydrogen-induced stress corrosion of pipeline steel induced by environmental and metallurgical factors
Effects of rare earth and chromium elements on the corrosion resistance of HRB400 rebar in concrete environments
Metallurgical defects on ductile iron corrosion mechanisms and corrosion big data-artificial intelligence techniques in revealing factors influencing material corrosion
Steel Corrosion and Metallurgical Factors strongly supports metallurgical and materials researchers and engineers in developing new corrosion-resistant steels.
