impact responses of rectangular composite plates with embedded shape memory alloy (sma) wires are investigated in the present research. the plate is assumed to be placed in a thermal environment; so that in contrast to the available researches in the field, the shape memory and ferroelasticity effects have to be considered also in addition to the superelasticity. the governing equations are der...

It is well known that applications of NiTi alloys in orthodontics rely on the pseudoelastic properties developed at temperatures hgher than Af. That implies as a necessary condtion that the body temperature (Tb) be higher than Af; the level of reversion stress, or depends moreover upon the difference between Tb and Af. Nowadays the interest is directed to obtain an archwire with distinct or in ...

The aim of this work is to provide a novel understanding pseudoelasticity mechanisms in an FeMnSi-based shape memory alloy and utilize the identified parameters control enhance mechanical behavior alloy. was processed by employing caliber rolling equivalent strain 0.25 at room temperature. Various heat treatments from 530 1000 °C were applied study microstructural evolution during short-term po...

Fabrication of nickel-titanium shape memory alloy through additive manufacturing has attracted increasing interest due to its advantages flexible capability, low-cost customization, and minimal defects. The process parameters in directed energy deposition (DED) have a crucial impact on molten pool characteristics (geometry, microstructure, etc.), thus influencing the final properties effect pse...

Among functional materials, quasiequiatomic NiTi alloys are one of the most promising and diffused for some sectors, from biomedical to aerospace ones. Their peculiar performance, namely, shape memory effect pseudoelasticity, is induced via a thermomechanical treatment called setting or with heat annealing. This carried out in cold-worked conditions. The present work studies material conditions...

The purpose of this review was to organize a systematic reference to help orthodontists evaluate commonly used orthodontic nickel-titanium alloys. Part I of the article reviewed the data available in the literature regarding the temperature transitional ranges of the alloys. The thermomechanical behavior of these compounds is, in fact, strictly dependent upon the correlation between the tempera...
