Many established, but also potential future applications of NiTi-based shape memory alloys (SMA) in biomedical devices and solid-state refrigeration require long fatigue life with 107–109 duty cycles1,2. However, improving the fatigue resistance of NiTi often compromises other mechanical and functiona...
Applications of shape-memory alloys include those as tubes and valves in piping systems for power plants, ships, and the petroleum industry; use as explosive bolts in the aerospace and construction industry; as packaging devices for electronic materials; and as dental materials, prosthetics, and bio...
Shape memory alloys Fibre reinforced polymer composites Processing Smart materials 1. Introduction The increasing need for weight-saving engineering solutions has led to the development of polymer matrix composite materials, now widely applied to aerospace, wind energy generation, sport as well as automoti...
This book provides a working knowledge of the modeling and engineering applications of shape memory alloys (SMAs), beginning with a rigorous introduction to continuum mechanics and continuum thermodynamics as they relate to the development of SMA modeling.Modern SMAs can recover from large amounts of...
For years it was speculated that the large strains associated with the thermoelastic shape-memory effect, such as in NiTi alloys, could be captured by application of a magnetic field in certain martensites that are also ferromagnetic. Ferromagnetic shape-memory alloys (FSMAs) moved from a hypothet...
