Investigating the Effects of Build Height on Mechanical Behavior of Large‐Scale Laser Wire Directed Energy Deposited Nickel Titanium Alloy

Advanced Engineering Materials, Volume 28, Issue 3, 4 February 2026.
Laser wire directed energy deposition process was leveraged to fabricate large scale NiTi alloy wall. Evaluation of build‐height‐dependent tribo‐mechanical properties revealed significant differences in location specific sample characteristics. The middle region achieved optimal performance (superior wear resistance, balanced strength‐ductility ...

Control of Covalent Bond Enables Efficient Magnetic Cooling

Advanced Materials, Volume 38, Issue 7, 2 February 2026.
Giant and reversible magnetocaloric effect (MCE) is achieved by tuning covalency through sub‐unit‐cell chemical engineering, establishing a novel design principle for effective hysteresis control in magnetocaloric materials. Abstract Magnetic cooling, harnessing the temperature change in matter when exposed to a magnetic field, presents an energy ...

Measurement of Elastoresistivity at Finite Frequency by Amplitude Demodulation

, 2018
Elastoresistivity, the relation between resistivity and strain, can elucidate subtle properties of the electronic structure of a material and is an increasingly important tool for the study of strongly correlated materials.

Elastocaloric effect vs fatigue life: Exploring the durability limits of Ni-Ti plates under pre-strain conditions for elastocaloric cooling

Acta Materialia, 2018
Abstract Structural fatigue is the major obstacle that prevents practical applications of the elastocaloric effect (eCE) in cooling or heat-pumping devices. Here, the eCE and fatigue behaviour of Ni-Ti plates are systematically investigated in order to define the fatigue strain limit and the associated eCE.

The Elastocaloric Effect in TiNi-based Foils

Materials Today: Proceedings, 2015
The elastocaloric effect in cold-rolled Ti49.1Ni50.5Fe0.4 foils of 30 μm thickness is studied by means of uniaxial tensile tests, digital image correlation and infrared thermography. During pseudoelastic cycling the evolution and orientation of Luders-like strain bands and the associated local release and absorption of latent heat depend on the rolling

Elastocaloric Effect Associated with the Martensitic Transition in Shape-Memory Alloys [PDF]

Physical Review Letters, 2008
The elastocaloric effect in the vicinity of the martensitic transition of a Cu-Zn-Al has been studied by inducing the transition by strain or stress measurements. While transition trajectories show significant differences, the entropy change associated with the whole transformation (\DeltaSt) is coincident in both kind of experiments since entropy ...
