Metallic glasses and their crystal/glass composites find ever more applications in such fields as mini transformers, microelectromechanical devices, pressure sensors, precision surgical instruments, biological implants and sportive goods (springs, diaphragms, membranes, knife blades, electromagnetic wave shields, optical mirrors, power inductors, Coriolis flow meters, etc.). The book reviews recent research and suggests future developments, e.g. in the area of dual-phase composite/hybrid materials.

In this presentation, we report the indentation behavior of Zr 69.5 Al 7.5−x Ga x Cu 12 Ni 11 (x = 0 and 1.5 at.%) metallic glasses as well as nanoquasicrystal–glass composites. The minor alloying addition in Zr -based glassy alloys greatly influences their mechanical properties. The nanoindentation tests were carried out to study the load (P) versus displacement (h) curves for the determination of reduced modulus as well as their hardness behavior. The formation of shear bands around the indentation periphery has been investigated. The evidence of the pile up was observed. The P − h curve for as-synthesized melt-spun ribbons displayed the presence of displacement burst, which are known as pop-ins. It has been concluded that Ga substitution leads to the improvement of the mechanical behavior of Zr–Al (Ga)–Cu–Ni alloys.

MOF crystal-glass composites (MOF CGCs) are materials with crystalline MOFs embedded within a MOF glass. Here we develop two novel MOF CGCs, and explore the gas uptake and guest-size limitations within these materials.

Science Field

Development of Fe-based bulk metallic glasses (BMG) with good mechanical and soft magnetic properties has become a major objective in the materials science field. Bulk metallic glasses present an interesting combination of properties. They exhibit very high strength (both in tension and compression), large elastic elongation limit, high hardness, excellent corrosion resistance, and good soft magnetic properties. These properties makes them suitable for many applications like high resistant control cables, pressure vessels, micro-components, pressure sensors, microgears for motors, magnetic cores for power supplies and hard fibers in composite materials. Multi-component Fe60Co14Ga2P10B5Si3Al3C3bulk metallic glass was synthesized in rod form with a diameter of 1 mm by copper mould casting technique using raw industrial materials. The obtained alloy was analyzed by X-ray diffraction (XRD), differential thermal analysis (DTA) and scanning electron microscopy (SEM) techniques, in order to determine the phase constituent, the thermal stability and the fracture surfaces of as-cast samples. The mechanical behaviour was investigated by microhardness and compression tests. The values recorded for hardness and fracture strength includes this alloy in the category of high resistant materials.

Using gas-atomized Ti-based metallic glassy powder, or the mixed powder blended with hydroxyapatite (HA) powder, we produced Ti-based bulk metallic glasses (BMGs) and the composites with high strength and satisfying large size requirements by a spark plasma sintering (SPS) process. The Ti-based BMGs and the composites with excellent properties and without toxic elements make it possible to apply as biomedical materials.

Thermo Physical Properties

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.
