The book "Fundamentals of Creep in Metals and Alloys," by the late Prof. Michael Ernest Kassner, focuses on the various facets of creep, a phenomenon involving time-dependent plasticity in materials at high temperatures.
Provides a basic description of creep
Outlines the objectives and scope of the book
Delves into the classic 'Five-Power-Law' creep behavior in metals and alloys
Discusses the relationship between strain rate, stress, and temperature
Explores the microstructural changes associated with creep deformation
Examines creep mechanisms based on the diffusion of atoms within materials
Covers Nabarro-Herring creep (volume diffusion) and Coble creep (grain boundary diffusion)
Introduces Harper-Dorn creep, a mechanism involving dislocation climb at low stresses
Discusses the theoretical models and experimental observations related to Harper-Dorn creep
Explores 'Three-Power-Law' creep, particularly in alloys
Explains the concept of viscous glide of dislocations as a creep mechanism
Discusses superplasticity, the ability of some materials to exhibit very large tensile elongations
Examines the microstructural characteristics of superplastic materials
Explores the role of recrystallization during creep deformation
Covers both discontinuous dynamic recrystallization (DRX) and geometric dynamic recrystallization (GDX)
Examines the creep behavior of alloys that are strengthened by the presence of second-phase particles
Discusses the concept of a 'threshold stress' for creep in such alloys
Focuses on the creep behavior of intermetallic compounds
Covers specific examples like titanium aluminides, iron aluminides, and nickel aluminides
Discusses the mechanisms of fracture during creep
Examines cavity nucleation and growth as critical factors leading to creep fracture
Explores the creep behavior of nickel-based superalloys, a class of high-temperature materials
Discusses the role of the γ/γ’ microstructure in creep
In essence, Prof. Kassner's book offers a comprehensive overview of the fundamental mechanisms and factors governing creep deformation and fracture in various metallic systems. It bridges theoretical concepts with experimental observations, providing a valuable resource for understanding the complexities of high-temperature material behavior.
