Features: This book is a comprehensive and systematic introduction to the research achievements at different levels concerning the relationship between the microstructure and strength-toughness of new steel materials. It incorporates the research findings of the author and colleagues over the years, as well as the latest advancements in domestic and international research. Starting with the essential fundamentals of metallurgy, the book presents the microstructure, mechanical properties, and their interrelationships of the new lead-free high-strength high-toughness steel G50 under different heat treatments. It also introduces the application of M?ssbauer spectroscopy technology in the study of the new lead-free high-strength high-toughness steel G50 and the lead-free secondary hardening steel G90. The book focuses on describing the application of electronic theory in materials science, including the study of grain boundary, dislocation electronic structure, solid solution strengthening, second-phase particle strengthening, and fine-grained strengthening mechanisms. Finally, it presents the use of artificial neural networks for the performance prediction and optimization design of new steel materials. This book can serve as a reference for teachers, researchers, and graduate students in universities and research institutions engaged in material research, especially steel materials.
