Fe–Mn–Al–Ni superelastic alloy is a potential candidate for diverse engineering applications due to its outstanding properties and low material costs. Recent studies suggest that slight changes in the chemical composition severely affect response, phase stability grain growth kinetics. In this paper, we found Al stabilizes parent α at high temperature promotes formation of β precipitation lower...

Abstract Martensitic phase transformation and plasticity are two primary mechanisms of deformation in shape memory alloys (SMAs) the interaction between them influences behaviour SMA during cyclic loading, specifically pseudoelasticity effect. This interaction, which occurs microscale, affects reversibility eventually actuation capacity SMAs. In order to capture this a discrete dislocation–tran...

In this issue, Butcher et al, 1 provide elegant data on the mechanical performance and material properties of stage 17, 21, and 25 chick embryonic atrioventricular (AV) cushions during normal development and following the selective digestion of AV cushion constituents. These data are then interpreted using a strain-energy based pseudoelasticity theory to determine maturational changes in AV cus...

Many models simulating the behavior of Shape Memory Alloys (SMA) exist nowadays, in the one or three dimensional situation. In most of the cases they are not able to describe the non isothermal behavior of SMA due to the thermomechanical loadings. Indeed, the influence of the stress on the product phase leads to an orientation of the variants, when the temperature creates a self-accomodating ma...

Electron beam powder bed fusion (PBF-EB) is used to manufacture dense nickel titanium parts using various parameter sets, including the current, scan speed and post cooling condition. The density of manufactured NiTi are investigated with relation linear energy input. results implies part increases increasing over 98% bulk density. With a constant input, combination low power leads denser parts...
