“…This Laves phase compound with an exact composition Tb 0.3 Dy 0.7 Fe 1.93 was developed by the Naval Ordnance Laboratory (NOL) and registered under the trade name Terfenol-D. It offers the highest strain of any magnetostrictive material, which makes it an excellent choice for applications in magnetomechanical sensors and actuators, for example, as acoustic and ultrasonic transducers [558,559,[564][565][566][567][568][569][570][571][572][573][574]. In a more recent study, further improvements of its magnetostrictive properties by partial substitution of Dy by Nd were reported [575].…”

“…An overview of the manifold applications of Terfenol-D is given by Olabi and Grunwald [565], for reviews on the magnetostrictive properties, see [577][578][579]. The spectrum of applications ranges from magnetostrictive underwater sound transducers in naval sonar systems [564] to more recent developments of magnetostrictive-piezoelectric composites of Terfenol-D and PZT (Pb(Zr,Ti)O 3 ) for energy harvesting to supply low-power electronics [573,574].…”

Laves phases with their comparably simple crystal structure are very common intermetallic phases and can be formed from element combinations all over the periodic table resulting in a huge number of known examples. Even though this type of phases is known for almost 100 years, and although a lot of information on stability, structure, and properties has accumulated especially during the last about 20 years, systematic evaluation and rationalization of this information in particular as a function of the involved elements is often lacking. It is one of the two main goals of this review to summarize the knowledge for some selected respective topics with a certain focus on non-stoichiometric, i.e., non-ideal Laves phases. The second, central goal of the review is to give a systematic overview about the role of Laves phases in all kinds of materials for functional and structural applications. There is a surprisingly broad range of successful utilization of Laves phases in functional applications comprising Laves phases as hydrogen storage material (Hydraloy), as magneto-mechanical sensors and actuators (Terfenol), or for wear- and corrosion-resistant coatings in corrosive atmospheres and at high temperatures (Tribaloy), to name but a few. Regarding structural applications, there is a renewed interest in using Laves phases for creep-strengthening of high-temperature steels and new respective alloy design concepts were developed and successfully tested. Apart from steels, Laves phases also occur in various other kinds of structural materials sometimes effectively improving properties, but often also acting in a detrimental way.

“…To solve those problems, a series of polymer–matrix composite doped by Terfeno‐D were prepared. [ 8–11 ] The ductility of these composites indeed has an improvement in a way but at the expense of the dramatic decrease in magnetostrictive properties. In addition, the rare‐element‐dependent feature for Terfenol‐D is difficult to reduce the production cost for wide industrialization.…”

Lightweight metal matrix composites have attracted a great attention for their technological application in aerospace, automotive, or sporting goods, and the multifunctionality of these composites will further expand the range of applications. Herein, a kind of lightweight 1–3 magnetostrictive FeCo/AlSi composites is investigated to evaluate the effects of the specific structure design and reverse magnetic field on the energy conversion under compression. The microstructure of the FeCo/AlSi composite before compression was observed, and the results indicate that there is a large bonding interface, which has the benefits of strain/stress transfer. Compared with the FeCo/AlSi composite with straight FeCo wire, a design with twisted FeCo wire significantly enhances the output performance of the magnetostrictive FeCo/AlSi composite. Furthermore, comparison of the output voltage for the FeCo/AlSi composite in the N–S mode (forward magnetization) and N–N mode (reverse magnetization) reveals that the reverse magnetization can improve the efficiency of the energy conversion notably. In addition, the results of the output voltage in the theoretical calculation are virtually consistent with that in practical measurement.

“…The increasing use of Terfenol-D in a wide variety of devices and systems such as sensors, actuators and transducers has driven the development of advanced manufacturing techniques to provide greater levels of strain performance, repeatability, rod size and production capacity (Issindou et al, 2018, Snodgrass andMcMasters, 1997). Such techniques include the free stand zone melting (FSZM) (Slaughter et al, 2004), modified bridgman (MB) (Moffett et al, 1991), sintered powder compact (Zhao et al, 2006), the ETREMA Crystal Growth (ECG) system , plasma processes (Issindou et al, 2018) and molecular beam epitaxy (Oderno et al, 1996). In order to produce nanoparticles of Terfenol-D Laser Ablation of Microparticles (LAM) can be used (Figure 23).…”
