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

open access: yesJournal 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.

Shape Memory Properties and Microstructure of New Iron-Based FeNiCoAlTiNb Shape Memory Alloys

open access: yesCrystals, 2021
The shape memory properties and microstructure of Fe41Ni28Co17Al11.5(Ti+Nb)2.5 (at.%) cold-rolled alloys were studied at the first time using the values reported in constant stress thermal cycling experiments in a three-point bending test.

Mechanocaloric effects in shape memory alloys [PDF]

open access: yesPhilosophical 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.

The effect of solution treatment temperature on SIEM and shape recovery of Fe–Mn–Si shape memory alloy

open access: yesJournal of Materials Research and Technology, 2021
Solution treatment process is stepwise process in manufacturing of iron based shape memory alloy. It is well known that the grain size of austenite in the solution treatment condition depends on the austenitizing/solutionizing temperature.

Some New Concepts of Shape Memory Effect of Polymers [PDF]

open access: yes, 2014
In this study some new concepts regarding certain aspects related to shape memory polymers are presented. A blend of polylactic acid (PLA) (80%) and polybutylene succinate (PBS) (20%) was prepared first by extrusion, then by injection molding to obtain ...

A method to determine the accuracy of shape setting thin, spirally shaped Nitinol wires

open access: yesCurrent Directions in Biomedical Engineering, 2021
Electric stimulation of the auditory nerve using a cochlear implant (CI) is presumed to be superior when the electrode array (EA) is placed close to the inner wall of the cochlea. Nitinol is investigated as an actuator that enables an intracochlear shape
