Design, Preparation and Properties of High Performance Steels

As the cornerstone of modern industry, the continuous performance breakthroughs in steel have been driven by a century of evolution in physical metallurgy. Today, research on high-performance steels not only pursues the ultimate balance between strength and toughness, but also focuses on meeting comprehensive performance requirements in demanding applications. This Reprint presents ten studies that highlight recent advances in steel performance via innovative alloy design and processing. The research covers a broad spectrum: from optimizing toughness and hardness in wear-resistant steel via double-quenching, to enhancing neutron absorption in gadolinium-bearing stainless steel for nuclear applications. Additional topics include oxidation resistance in ferritic stainless steel, center property refinement in ultra-heavy plates, toughness mechanisms in ultra-high-strength casing, microstructure-property relationships in medium-manganese steel, precipitate behavior in fire-resistant steel, and carbide effects in martensitic stainless steel. Through analyses of work-hardening behavior and fracture toughness, this volume elucidates the intrinsic links between microstructural characteristics and macroscopic mechanical properties. Collectively, these contributions highlight the core principles of physical metallurgy, demonstrating how material performance can be tailored through precise alloy design and microstructural adjustment. We hope this Reprint serves as a theoretical reference and practical guide for researchers and engineers in the fields of materials science and industrial manufacturing.
