Pearlitic steel is the strongest commercially available mass-produced alloy, and pearlite is used in a myriad of applications, from the reinforcement of tyres in every single road vehicle in the world to the creation of pathways across troubled waters. Pearlite in Steels is the first book dedicated to this vast subject. The book uniquely covers the topic in-depth, providing comprehensive coverage of fundamentals and technologies that make pearlite vital as an engineered material. This book covers the 3D structure of pearlite over a wide range of length scales, details the relationship between imperfect structure and consequences, discusses all aspects of structure and complex properties, covers the evolution of structure during traumatic processing, highlights the engineering aspects: the twisting of pearlitic wires, for the safe application of the strongest of ropes in safety-critical scenarios and highlights difficulties and inconsistencies, thereby helping to develop research. Aimed at materials engineers and metallurgists, this book by a leading global authority on the subject offers readers the deepest and broadest overview of pearlite in steels to date.
