“…18 and 19 for an overview on the technique and its potential applications), which have been successfully applied to SMA both as thin films and bulk materials to characterize their thermomechanical properties and their evolution with thermal treatments. [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] However, the multiaxial nature of deformation around the nanoindenter renders quantitative interpretation of the data very complex, especially for SMA which exhibit strong nonlinear behavior during thermal-or stress-induced transformation. This difficulty, together with interest in developing three-dimensional SMA devices for MEMS, has moved attention toward the use of nanocompression tests on simple features like micro and nanopillars produced by focused ion beam (FIB) milling.…”

Thermomechanical behavior at the nanoscale and size effects in shape memory alloys

Shape memory alloys (SMA) undergo reversible martensitic transformation in response to changes in temperature or applied stress, resulting in the properties of superelasticity and shape memory. At present, there is high scientific and technological interest to develop these properties at small scales and apply SMA as sensors and actuators in microelectromechanical system technologies. To study the thermomechanical properties of SMA at micro and nanoscales, instrumented nanoindentation is widely used to conduct nanopillar compression tests. By using this technique, superelasticity and shape memory at the nanoscale have been demonstrated in micro and nanopillars of Cu-Al-Ni SMA. However, the martensitic transformation seems to exhibit different behavior at small scales, and a size effect on superelasticity has been recently reported. In this study, we provide an overview of the thermomechanical properties of Cu-Al-Ni SMA at the nanoscale, with special emphasis on size effects. Finally, these size effects are discussed in light of the microscopic mechanisms controlling the martensitic transformation at the nanoscale.

“…Since in their martensitic state, they are mechanically soft, nanoindentation mapping of elastic modulus has been effectively used to identify martensite composition regions. 422 Another method for detection of the martensitic transition is through implementation of arrays of cantilevers, since the change in the elastic modulus of the film deposited atop the cantilever as a result of the martensitic transition results in an abrupt deflection. 108 Indeed, cantilever arrays have served as a versatile combinatorial platform for mapping a variety of mechanical properties such as film stresses, glass transitions, and fatigue.…”

High throughput (combinatorial) materials science methodology is a relatively new research paradigm that offers the promise of rapid and efficient materials screening, optimization, and discovery. The paradigm started in the pharmaceutical industry but was rapidly adopted to accelerate materials research in a wide variety of areas. High throughput experiments are characterized by synthesis of a "library" sample that contains the materials variation of interest (typically composition), and rapid and localized measurement schemes that result in massive data sets. Because the data are collected at the same time on the same "library" sample, they can be highly uniform with respect to fixed processing parameters. This article critically reviews the literature pertaining to applications of combinatorial materials science for electronic, magnetic, optical, and energy-related materials. It is expected that high throughput methodologies will facilitate commercialization of novel materials for these critically important applications. Despite the overwhelming evidence presented in this paper that high throughput studies can effectively inform commercial practice, in our perception, it remains an underutilized research and development tool. Part of this perception may be due to the inaccessibility of proprietary industrial research and development practices, but clearly the initial cost and availability of high throughput laboratory equipment plays a role. Combinatorial materials science has traditionally been focused on materials discovery, screening, and optimization to combat the extremely high cost and long development times for new materials and their introduction into commerce. Going forward, combinatorial materials science will also be driven by other needs such as materials substitution and experimental verification of materials properties predicted by modeling and simulation, which have recently received much attention with the advent of the Materials Genome Initiative. Thus, the challenge for combinatorial methodology will be the effective coupling of synthesis, characterization and theory, and the ability to rapidly manage large amounts of data in a variety of formats.

“…A similar study was conducted on Ni-Mn-Al alloy system, where it was seen that both ferromagnetic and shape memory properties coexisted [118]. High-throughput screening using nanoindentation was performed on Ni-Mn-Al thin-film composition spreads to delineate martensitic regions, which were found to have low elastic modulus and hardness [119]. …”

Ferromagnetic Shape Memory Heusler Materials: Synthesis, Microstructure Characterization and Magnetostructural Properties

et al. 2018

View full text Add to dashboard Cite

An overview of the processing, characterization and magnetostructural properties of ferromagnetic NiMnX (X = group IIIA–VA elements) Heusler alloys is presented. This type of alloy is multiferroic—exhibits more than one ferroic property—and is hence multifunctional. Examples of how different synthesis procedures influence the magnetostructural characteristics of these alloys are shown. Significant microstructural factors, such as the crystal structure, atomic ordering, volume of unit cell, grain size and others, which have a bearing on the properties, have been reviewed. An overriding factor is the composition which, through its tuning, affects the martensitic and magnetic transitions, the transformation temperatures, microstructures and, consequently, the magnetostructural effects.
