One-way and two-way shape memory effect in ferromagnetic NiFeGaCo single crystals

, 2020
The effects of stress-free and stress-assisted aging at 673 K for 4 h on the one-way and two-way shape memory effect (TWSME) in ferromagnetic Ni49Fe18Ga27Co6 (at%) single crystals were investigated.

Laser-Induced Two-Way Shape Memory Effect in TiNiCu Films of Different Thicknesses

Nanomanufacturing and Metrology
Shape memory alloys (SMAs) can recover their original shape after deformation when heated above a specific transformation temperature. This study investigates the induction of the two-way shape memory effect (TWSME) in SMA films through laser surface ...

Two-way Shape Memory Effect of NiTi under Compressive Loading Cycles [PDF]

, 2011
In this study, the two-way shape memory effect (TWSME) of a Ni-54.5 at.% Ti alloy was investigated experimentally to develop a NiTi linear actuator. The two-way shape memory effect was induced through a compressive shape memory cycle composed of four ...

TRAINING AND THE TWO WAY MEMORY EFFECT IN COPPER BASED SHAPE MEMORY ALLOYS [PDF]

Le Journal de Physique IV, 1991
Experimental results giving information about the mechanisms of the two way memory effect are presented. It is shown that local martensite stabilization and true plastic deformations have to be considered as undesirable side-effects of training.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Effect of aging on the martensitic transformation and functional properties of a Ni44.8Ti45.2Hf5Cu5 multi component shape memory alloy

Discover Mechanical Engineering
In this study, a Ni44.8Ti45.2Hf5Cu5 shape memory alloy was fabricated by vacuum arc-melting in a copper mold. The alloy was solution annealed at 1000 °C for 60 min and subsequently aged at a temperature range between 300 °C and 600 °C for different time ...

Temperature memory effect in two-way shape memory TiNi and TiNiCu springs [PDF]

Journal of Materials Science, 2006
An incomplete thermal cycle upon heating in a shape memory alloy (arrested at a temperature between As and Af) induced a kinetic stop in the next complete thermal cycle. The kinetic stop temperature is closely related to the previous arrested temperature. This phenomenon is named temperature memory effect (TME).

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Martensitic Tweed and the Two-Way Shape-Memory Effect

, 1997
We briefly introduce tweed, which is found above the martensitic transition in a variety of shape-memory, high-T_c, and other materials. Based on our previous mapping of the problem onto a spin-glass model, we conjecture that the two-way shape-memory effect is due to tweed.
