Abstract: Under conditions of static and dynamic loading to high pressures or stresses, it can be critical to quantify the strength of a material and it is well understood that material microstructure controls properties like strength. It is also expected that microstructures, particularly for many ...

Shape-memory alloy
A shape-memory alloy (SMA, smart metal, memory metal, memory alloy, muscle wire, smart alloy) is an alloy that ""remembers"" its original shape and that when deformed returns to its pre-deformed shape when heated. This material is a lightweight, solid-state alternative to conventional actuators such as hydraulic, pneumatic, and motor-based systems. Shape-memory alloys have applications in industries including automotive, aerospace, biomedical and robotics.
