Special Issue Information

Dear Colleagues,

Metallic glasses (or amorphous alloys) are currently attracting increased interest due to their unique physical-mechanical properties such as high hardness, large elastic deformation, and high fatigue strength, as well as increased wear resistance and corrosion resistance. Numerous studies show that metal glassy alloys have significantly higher mechanical properties than their crystalline analogs. However, due to the peculiarities of their atomic structure, this class of materials is prone to brittle fracture and has extremely low ductility. In this regard, creating composite materials based on metallic glasses could help to avoid most of the disadvantages. For this Special Issue in Metals, we aspire to publish a range of articles covering (i) the preparation of the metal glassy alloys and their composites (amorphous/crystalline composites, metal/polymer composites, etc.), (ii) structural investigation of the materials, based on metallic glasses (in solid or liquid state), (iii) properties investigation of the obtained composites materials (mechanical, physical, chemical, biological, etc.), and (iv) applications of the final products, based on metal glassy alloys and their composites (including ribbon, bulk, powder, coatings, thin-films, etc.).

I would like to invite you to submit original contributions to this Special Issue that may take into account any of the materials aspects mentioned above. We are looking forward to receiving regular research papers, reviews, and short communications.

Abstract

The processing route of Sm₂Fe₁₇ carbides is shorter than that of nitrides, which can potentially be used for cost-effective mid-performance magnets’ production. The magnetic properties of Sm₂Fe₁₇C_x compounds can be controlled at the annealing step, which allows them to be used for a variety of applications. In this work, X-ray diffraction (XRD) analysis, Mössbauer spectroscopy, scanning and transmission electron microscopy (SEM, TEM) and vibrating sample magnetometry (VSM) were used for characterization of the structure and magnetic properties of Sm₂Fe₁₇C_x compounds. The powder samples were prepared by high-energy ball milling of Sm₂Fe₁₇ mixtures with carbon nanotubes (CNT) or graphite with subsequent annealing. The formation of Sm₂Fe₁₇C_x compounds after annealing was followed by the formation of α-Fe and amorphous Sm₂O₃. The hyperfine field values of Fe atoms of all the Sm₂Fe₁₇ lattice sites increased by 12% on average after annealing that was caused by carbon diffusion. The coercivity of the samples peaked after annealing at 375 °C. The samples with CNT demonstrated an increase of up to 14% in coercivity and 5% in specific remanence in the range of 250–375 °C annealing temperatures. Full article

Abstract

A scanning magnetometer based on a magnetoimpedance sensor with a 1 mm spatial resolution and 10 nT sensitivity was used to study stray magnetic fields of Fe₇₄B₁₃Si₁₁C₂ amorphous ferromagnetic microwires. Spatial magnetic images and vertical component profiles of stray magnetic fields of the studied microwires were obtained in a longitudinal homogeneous magnetic field of Helmholtz coils with a strength in the range of ±600 A/m. A magnetic calculation method is suggested that allows for using the measured magnetic fields to determine the magnitude and pattern of magnetization for the microwire. Characteristic values of the microwires’ average magnetization and width of closure domains for various values of bias fields were found. Full article

Abstract

A method for the determination of the thermal conductivity of polymer composite materials by using Co-based ferromagnetic microwires is proposed. Microwire segments were integrated into the samples of studied materials during their manufacture and used as current microheaters and resistance thermometers. As a representative material, we used a material based on nitrile butadiene rubber filled with hexagonal boron nitride after its low-temperature carbonization and a significant increase in thermal conductivity. The thermal conductivity values of composite samples determined during experiments varied from 1.0 W/(m·K) to 1.8 W/(m·K) depending on the percentage of boron nitride. The thermal conductivity values obtained are in good agreement with the estimates obtained by the standard laser flash method. Full article

Effect of Oxygen Flow Rate on Properties of Aluminum-Doped Indium-Saving Indium Tin Oxide (ITO) Thin Films Sputtered on Preheated Glass Substrates

by Svitlana Petrovska, Ruslan Sergiienko, Bogdan Ilkiv, Takashi Nakamura and Makoto Ohtsuka

Abstract

Amorphous aluminum-doped indium tin oxide (ITO) thin films with a reduced indium oxide content of 50 mass% were manufactured by co-sputtering of ITO and Al₂O₃ targets in a mixed argon–oxygen atmosphere onto glass substrates preheated at 523 K. The oxygen gas flow rate and heat treatment temperature effects on the electrical, optical and structural properties of the films were studied. Thin films were characterized by means of a four-point probe, ultraviolet–visible-infrared (UV–Vis-IR) spectroscopy and X-ray diffraction. Transmittance of films and crystallization temperature increased as a result of doping of the ITO thin films by aluminum. The increase in oxygen flow rate led to an increase in transmittance and hindering of the crystallization of the aluminum-doped indium saving ITO thin films. It has been found that the film sputtered under optimal conditions showed a volume resistivity of 713 µΩ cm, mobility of 30.8 cm²/V·s, carrier concentration of 2.9 × 10²⁰ cm⁻³ and transmittance of over 90% in the visible range.

by Adit Sharma and Vladislav Zadorozhnyy

Abstract

Metallic glasses are known for their mechanical properties but lack plasticity. This could be prevented by combining them with other materials or by inducing a second phase to form a composite. These composites have enhanced thermo-physical properties. The review paper aims to outline a summary of the current research done on metallic glass and its composites. A background in the history, properties, and their applications is discussed. Recent developments in biocompatible metallic glass composites, fiber-reinforced metallic glass, ex situ and in situ, are discussed. Full article
