In metallurgy, a shape-memory alloy (SMA) is an alloy that can be deformed when cold but returns to its pre-deformed ("remembered") shape when heated. It may also be called memory metal, memory alloy, smart metal, smart alloy, or muscle wire. Parts made of shape-memory alloys can be lightweight, solid-state alternatives to conventional actuators such as hydraulic, pneumatic, and motor-based systems. They can also be used to make hermetic … Webb16 juni 2024 · Engineers at Texas A&M University conducting a study supported by the U.S. National Science Foundation have created a superelastic shape memory alloy using 3D printing. Their method avoids defects like warping and delamination that commonly occur when 3D printing with laser powder bed fusion. Webbencapsulation of the shape memory alloy tube has been proposed. The proposed encapsulation is based on a shape memory alloy tube, as shown in (Figure 2). For small stresses, shape memory alloys function in a super elastic way that enables them to absorb vibrations and dissipate them energetically either thermally or thermos mechanically. how many records did mariah carey sell
