Superalloys: Elsevier - Health Sciences Division Superalloys: Strengthening Behavior of Precipitating Phases Paperback

Superalloys: Strengthening Behavior of Precipitating Phases covers the strengthening mechanisms associated with all types of precipitates that form in superalloys, synthesizing a vast body of literature on the strengthening behavior of these phases, with each chapter introducing fundamental metallurgical principles to help readers develop a clear understanding. The book provides an in-depth exploration of the deformation mechanisms of intermetallic phases in superalloys, focusing on the interaction between matrix dislocations and these phases. Chapter 1 provides an overview of superalloys, their classifications, compositions, and the various strengthening phases, also covering the reasons behind the varying strengthening behavior of different precipitates. Chapter 2 lays the foundation for understanding deformation and strengthening mechanisms in metals and alloys. Chapters 3, 4, and 5 each focus on strengthening behavior and mechanisms of specific precipitates, γ′, γ″, and Ni2(Cr,Mo), respectively. Chapter 6 discusses the strengthening effects of the δ and η phases, which form at intermediate temperatures and play a crucial role in controlling grain size, enhancing creep, and fatigue resistance. Chapter 7 examines the role of other strengthening agents, including oxides, borides, and carbides that improve high-temperature strength by impeding dislocation motion and grain boundary sliding.
