Phase transformation and shape memory effect of a Cu-Al-Ni-Mn-Nb high temperature shape memory alloy
(Elsevier Science, 2016-04)
The microstructure, phase transformation and shape memory effect of the high temperature shape memory alloy Cu-11.4Al-3.2Ni-3Mn-0.5 Nb (wt%) were investigated for the first time. The shape recovery ratio can achieve 73% ...
A simple model to predict long-range atomic ordering temperatures in Cu-based shape memory alloys
(Taylor & Francis, 2014-06)
The order–disorder and order–order phase transition temperatures in the austenitic phase of Cu-based shape memory alloys were used to obtain a set of first- and second-neighbour pair interchange energies. To this end, a ...
Influence of the microstructure on the corrosion behaviour of a shape memory Cu–Al–Be alloy in a marine environment
(Elsevier Science, 2011-01-20)
The influence of the microstructure on the corrosion behaviour of a shape memory Cu–11.40Al–0.55Be (wt.%) polycrystalline alloy in 3.5% NaCl has been studied by microscopical examinations, spectroscopical and X-ray diffraction ...
Effect of parent austentite grain size on the number of variant orientations of stainless shape memory alloy effects

Chaos control of a nonlinear oscillator with shape memory alloy using an optimal linear control: Part I: Ideal energy source
(Springer, 2009-01-01)
In this paper, an optimal linear control is applied to control a chaotic oscillator with shape memory alloy (SMA). Asymptotic stability of the closed-loop nonlinear system is guaranteed by means of a Lyapunov function, ...
Active angular control of a sectioned airfoil using shape memory alloys and fuzzy controller
(2015-09-01)
The present work illustrates an example of shape memory alloys and fuzzy controllers applied to active angular control of a sectioned airfoil. The main objective of the proposed control system is to modify the camber line ...
Spinodal decomposition and martensitic transformation in Cu–Al–Mn shape memory alloy
(Springer, 2017-12)
Isothermal treatments at 413 K were performed in Cu–Al–Mn shape memory alloy samples, to study their effects on the martensitic transformation. This procedure, within the miscibility gap, produces spinodal decomposition. ...
Modeling and Experimental Aspects of Self-healing Bolted Joint through Shape Memory Alloy Actuators
(Sage Publications Ltd, 2011-09-01)
Bolted joints are a form of mechanical coupling largely used in machinery due to their reliability and low cost. Failure of bolted joints can lead to catastrophic events, such as leaking, train derailments, aircraft crashes, ...
Aeroelastic Analysis of a Typical Section Using of Shape memory wire actuator
(2011)
Shape memory alloys (SMAs) provide a compact and effective actuation for a variety of mechanical systems. In this paper, a numerical simulation study of a three degree of-freedom airfoil, subjected to two-dimensional ...
Effects of grain size on plastic deformation in a β CuAlBe shape memory alloy
(Elsevier Science, 2014-02)
The effects of grain size on the deformation under compression of a β Cu–11.4Al–0.5Be (wt%) polycrystalline shape memory alloy were analyzed. As the maximum stress increases, major levels of pseudoelastic strain are obtained ...
