Shape Memory Alloy

Shape memory materials are fascinating materials, with the potential for application as "smart materials" and also as new functional materials. This book presents a systematic and up-to-date account of all aspects of shape memory materials, from fundamentals to applications. Starting from the basic principles of the martensitic transformation, on which the shape memory effect and the superelasticity of alloys are based, the mechanisms of the two phenomena are clearly described, together with possible applications. The characteristics, fabrication techniques and thermomechanical treatment of various shape memory alloys are described in detail, with special emphasis on Ti-Ni and Ti-Ni-X (with X being Cu, Fe etc.) alloys. The book then describes various applications and design principles, for example in actuators, medical applications and as smart materials. The book contains chapters on shape memory ceramics and polymers as well as shape memory alloys, making the book a comprehensive account of the field.

This monograph contributes to the mathematical analysis of systems exhibiting hysteresis effects and phase transitions. Its main part begins with a detailed study of models for scalar rate independent hysteresis in the form of hysteresis operators. Applications to ferromagnetism, elastoplasticity and fatigue analysis are presented, and two representative distributed systems with hysteresis operator are discussed. The attention then shifts to the mechanisms of energy dissipation and transformation that induce a hysteretic behavior in continuous media undergoing phase transitions. After an introduction to phenomenological thermodynamic theories of phase transitions, in particular, the Landau-Ginzburg theory and phase field models, several specific models are discussed in detail. These include Falk's model for the hysteresis in shape memory alloys and the phase field models due to Caginalp and Penrose-Fife. The latter are studied both for conserved and non-conserved order parameters. A chapter presenting a mathematical model for the austenite-pearlite and austenite-martensite phase transitions in eutectoid carbon steels concludes the book.

Shape memory alloy - A shape memory alloy (SMA) (also known as memory metal or smart wire) is a metal that remembers its geometry. After it is deformed, it regains its original geometry by itself during heating (one-way effect) or, at higher ambient temperatures, simply during unloading (pseudo-elasticity).

Magnetic shape memory - Magnetic shape-memory (MSM) alloys are ferromagnetic materials exhibiting large changes in shape and size in an applied magnetic field.

Superelasticity - Superelastic alloys belong to the larger family of shape-memory alloys. When mechanically loaded, a superelastic alloy deforms reversibly to very high strains - up to 10% - by the creation of a stress-induced phase.

Non-Uniform Memory Access - Non-Uniform Memory Access or Non-Uniform Memory Architecture (NUMA) is a computer memory design used in multiprocessors, where the memory access time depends on the memory location relative to a processor. Under NUMA, a processor can access its own local memory faster than non-local memory, that is, memory which is local to another processor or shared between processors.
