Ultrashort Laser Texturing of Superelastic NiTi: Effect of Laser Power and Scanning Speed on Surface Morphology, Composition and Wettability

open access: yesMetals, 2023
Among metallic biomaterials, near-equiatomic NiTi is one of the most promising intermetallic system applicable for biomedical applications, thanks to its high biocompatibility and unique superelasticity (or pseudoelasticity), offering a complete ...

Eco‐Friendly Concrete: Experimental Study on the Mechanical Properties of Recycled Concrete Aggregates and Shape Memory Alloy‐Infused Mixtures

open access: yesThe Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
This experimental study investigates the combined use of RCAs and SMA fibres to enhance concrete's sustainability and mechanical properties. Results showed that adding SMA to RCA mixtures increased compressive, splitting tensile and flexural strengths, while the SMA's shape memory effect (SME) contributed to a closer restoration of the initial strength

Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

open access: yesAdvanced Materials, Volume 37, Issue 51, December 23, 2025.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic

Pseudoelasticity in Fe3Ga with boron-A combined atomistic-micromechanical treatment [PDF]

open access: yes, 2015
The Fe3Ga base alloy is known to exhibit pseudoelasticity and the solute hardened Fe3GaB holds considerable promise as well. The present work aims at developing a theoretical model to establish the critical twinning stress in Fe3Ga with varying boron ...

Global Nonlinear Dynamics of a Calibrated Pseudoelastic SMA-Wire Oscillator: Multistability, Basin Structure and Routes to Chaos

open access: yesVibration
Hysteretic nonlinear vibration systems can exhibit jumps, coexisting attractors, and strong dependence on the initial state, particularly when material hysteresis is coupled with geometric nonlinearity.

Micromechanical Insights into Sinter‐Based Additively Manufactured NiTi with Nb as a Sintering Aid

open access: yesAdvanced Engineering Materials, Volume 27, Issue 21, November 2025.
This study investigates the microstructural and micromechanical behavior of NiTiNb made through filament‐based materials extrusion via chemically correlated nanoindentation. B19' remnants from the original powder lead to Nb gradients within NiTiNb grains due to the short sintering times required in liquid‐phase sintering.

Structural Changes Associated with the Pseudoelastic Response of Fe-Based Shape Memory Alloys

open access: yesThe Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2014
The pseudoelastic responses of two types of iron base shape memory alloys (SMAs) were introduced and discussed. The former was based on Fe-Mn-Si system, obtained by classical (CM) and by powder metallurgy (PM) manufacturing. The latter was based on Fe-Ni-

Autonomous Implants

open access: yesAdvanced Materials, Volume 37, Issue 45, November 13, 2025.
An ideal implant should mimic native tissues such that it can integrate, sense, heal, and continue to function, i.e., be autonomous. Although early, there are good steps taken in this way, e.g., the development of stimuli‐responsive, self‐powering, self‐actuating, self‐healing, self‐regenerating, and self‐aware implants.
