Shape memory effect in FeMnNiAl iron-based shape memory alloy

Scripta Materialia, 2019
The development of Iron-based shape memory alloys holds significant promises for cost-sensitive applications. FeMnNiAl has been attracting increasing interest due to high levels of superelasticity across a wide range of temperatures (−196–300 °C ...

Effect of solidification modes on the shape memory effect of cast Fe-Mn-Si-Cr-Ni shape memory alloys

Journal of Materials Research and Technology, 2023
We investigated the microstructures and shape memory effect (SME) of cast Fe-Mn-Si-Cr-Ni alloys with four solidification modes, i.e., austenitic, austenitic-ferritic, ferritic-austenitic, and ferritic modes.

Mechanocaloric effects in shape memory alloys [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016
Shape memory alloys (SMA) are a class of ferroic materials which undergo a structural (martensitic) transition where the associated ferroic property is a lattice distortion (strain). The sensitiveness of the transition to the conjugated external field (stress), together with the latent heat of the transition, gives rise to giant mechanocaloric effects.
