Smart Materials and Structures, 2007
This special issue on shape memory alloys (SMA) is an encore to a special issue on the same topic edited by us six years ago (Smart Mater. Struct. 9 (5) October 2000). A total of 19 papers is offered in this issue, organized into the three broad categories of modeling, characterization and applications.

MRS Bulletin, 1993
Numerous metallic alloys are now known to exhibit a shape memory effect through which an article deformed at a lower temperature will regain its original undeformed shape when heated to a higher temperature. This behavior is basically a consequence of a martensitic phase transformation.

Shape memory alloys. Ultralow-fatigue shape memory alloy films.
Science (New York, N.Y.), 2015Functional shape memory alloys need to operate reversibly and repeatedly. Quantitative measures of reversibility include the relative volume change of the participating phases and compatibility matrices for twinning. But no similar argument is known for repeatability.

Abstract The term shape memory alloys (SMAs) refers to the group of metallic materials that demonstrate the ability to return to some previously defined shape or size when subjected to the appropriate thermal procedure. Materials that exhibit shape memory only upon heating are referred to as having a one-way shape memory.

Advanced Engineering Materials, 2004
The purpose of this study is to build a fundamental understanding of the relationship between the structure and properties of cast nickel‐titanium (NiTi). The structure of the cast material will be analyzed at various scales and will be related to the properties of the cast material such as transformation temperatures, stress‐strain behavior, and ...

Multiple Memory Shape Memory Alloys
Advanced Engineering Materials, 2013AbstractUntil now, shape memory alloys (SMAs) have been largely limited to “remembering” a single memory. In other words, monolithic components only possess a single set of functional properties. The current work describes how theorized change to local chemical composition induced through laser processing enables controlled augmentation of ...

Phenomenology of Shape Memory Alloys
2015The strong demand for high performance structural and mechanical systems for aerospace, defense, and advanced manufacturing industries has promoted the evolution of advanced materials. Materials cannot respond to changes of the surrounding environment and are not able to operate under the service conditions for which they are not optimally designed ...
