Abstract:

The single crystal Ni-Mn-Ga and Ni-Mn-Ga particulate composites have responded to mechanical stress up to 1 kHz frequencies with significant acoustic attenuation. It has been observed that in Ni-Mn-Ga polymer composites, a heavy static load on both the ends of the system increases the acoustic stress amplitude and appears to have acoustic loss drops. The attenuation, as a function of frequency shows resonances in the displacement of the vibrating particle indicating the twin boundary motions. It is inferred that the resonances beyond the principal mode are highly damped in the Ni-Mn-Ga composi

Abstract:

The ferromagnetic shape memory alloy polyurethane, Ni-Mn-Ga-PU, polymer composites absorb more mechanical energy than the conventional materials used for vibration damping applications. The vibration damping has been investigated using the custom-made experimental setup. The computed resonance peak values are in agreement with the experimental data. The dilatational wave decreases at high frequencies which is consistent with the theory of resonance frequency. The previously free end of the system increases the amplitude stress for an appreciable static load but loss appears to be very small. T

Abstract:

In the search for new magnetic functional materials, non-stoichiometric compounds remain a relatively unexplored territory. While experimentalists create new compositions looking for improved functional properties, their work is not guided by systematic theoretical predictions. Being designed for perfect periodic crystals, the majority of first-principles approaches struggle with the concept of a non-stoichiometric system. In this work, we attempt a systematic computational study of magnetic and structural properties of Ni–Mn–Ga, mapped onto ternary composition diagrams. Compositional stabilit

Abstract:

The giant magnetically-induced deformation of ferromagnetic shape memory alloys results from the magnetic field-induced rearrangement of twinned martensite under the magnetic field. This deformation is conventionally referred to as the magnetic-field-induced-strain (MFIS). The MFIS is comparable in value with the spontaneous deformation of crystal lattice during the martensitic transformation of an alloy. Although the first observations of MFIS were reported more than 30 years ago, it has got a world-wide interest 20 years later after the creation of the Ni–Mn–Ga alloy system with its practica

With the purpose to optimize the functional properties of Heusler alloys for their use in solid-state refrigeration, the characteristics of the martensitic and magnetic transitions undergone by Ni50Mn25−xGa25Cux (x = 3–11) alloys have been studied. The results reveal that, for a Cu content of x = 5.5–7.5, a magnetostructural transition between paramagnetic austenite and ferromagnetic martensite takes place. In such a case, magnetic field and stress act in the same sense, lowering the critical combined fields to induce the transformation; moreover, magnetocaloric and elastocaloric effects are b

В настоящей работе представлены результаты комплексных исследований влияния деформации, полученной методом всесторонней изотермической ковки, на магнитокалорические свойства сплава Гейслера на основе Ni-Mn-Ga. Прямые измерения адиабатического изменения температуры показали, что в результате циклирования образца в магнитном поле μΔH-1,85Тл, ΔT(T) может уменьшаться на величину, соответствующую необратимому изменению температуры на этапе первого цикла намагничивания, связанному с выделением срытой теплоты перехода. Пренебрежение этим эффектом приводит к завышенной оценке магнитокалорического эффе

The article deals with the determining characteristics of ore elements in the Goshgarchay porphyry-epithermal system. The genetic and geochemical characteristics of the main ore components were studied, and close positive and negative relationships between pairs of elements were determined by correlation analysis on the selected elements. According to the results of the cluster analysis, the geochemical associations that allow the localization of the development area of mineralization at different stages of formation of the porphyry-epithermal system were analyzed.

Complex chalcogenides based on transition elements, in particular ternary compounds of the АВ2Х4 type (M = Mn, Fe, Co, Ni; B = Ga, In, Sb, Bi; X = S, Se, Te) are among the important functional materials. Compounds of this class exhibit the phenomena of electronically or optically controlled magnetism and are very promising for the creation of lasers, light modulators, photodetectors, and other functional devices controlled by a magnetic field. Recent studies demonstrated that these compounds can also find application in photocatalysis, photovoltaics, and thermoelectric converters. The study pr

The results of the calculation show that the effect of ternary additions on the distortion of TiAl lattice varies with the substitution behavior of the individual alloying element involved. The addition of alloying elements in TiAl causes a change in the electronic structure and the density of states of the

The samples were digested in a microwave system using the wet digestion method. The minerals were determined by the application of inductively coupled plasma-atomic emission spectrometry (ICP-AES) and inductively coupled plasma-mass spectrometry (ICP-MS).

Abstract:

Magnetic shape memory Heuslers have a great potential for their exploitation in next-generation cooling devices and actuating systems, due to their “giant” caloric and thermo/magnetomechanical effects arising from the combination of magnetic order and a martensitic transition. Thermal hysteresis, broad transition range, and twinning stress are among the major obstacles preventing the full exploitation of these materials in applications. Using Ni-Mn-Ga seven-modulated epitaxial thin films as a model system, we investigated the possible links between the phase transition and the details of the t

Abstract:

Typically, steel is protected from corrosion by employing sacrificial anodes or coatings based on Zn, Mg, Al or Cd. However, stricter environmental regulations require new environmentally friendly alternatives to replace Cd. Traditionally, Al-based anodes have been employed to cathodically protect steel in marine applications or as ion vapour deposition (IVD)-Al sacrificial coatings for aerospace applications. However, Al tends to passivate, thus losing its protective effect. Therefore, it is important to identify possible alloys that can provide a constantly sufficient current. In this study,
