Resumen:

© 2026 selection and editorial matter, Ajit Behera and Manisha Priyadarshini; individual chapters, the contributors.Alloys with shape memory and pseudoelasticity effects are distinguished by their ability to return to their original shape through an external stimulus after being deformed. These alloys can exhibit both unidirectional and bidirectional shape memory effects, as well as pseudoelasticity. Pseudoelasticity, on the other hand, refers to the recovery of the material?s original shape once the stress that caused the deformation is removed. The extent of deformation that an alloy can experience depends on its composition and structure, and in some cases, it can be several times greater than the maximum elastic deformation. Currently, various systems have been developed that can exhibit all these properties, which are due to nondiffusive solid?solid structural transitions between the austenite and martensite phases or to martensitic transformations induced thermally or mechanically. Additionally, these alloys often require specific thermomechanical treatments, such as ?training treatment,? especially in cases where the alloy needs to exhibit a bidirectional shape memory effect. Metals commonly used in the design of shape memory and pseudoelastic alloys include Fe, Si, Cr, Co, Ti, Al, Ni, Nb, and Mn, among others, with C, N, O, etc. as interstitial elements. Despite this knowledge, this field requires continuous research to enable technological advancement.
