The measurement of fragility of glass-forming liquids involves either the determination of viscosity at different temperatures above the glass transition or the measurement of the dynamic glass–liquid transition by ...

The effect of minor transition metals and rare earths on glass-forming ability, thermal stability and crystallization of [(Fe0.6Co0.4)0.75Si0.05B0.20]96-xNb4Mx alloys was investigated. The thermodynamic parameters traditionally ...

There is a marked correlation between the composition, microstructure and properties in TiCN-based cermets. In the case of using iron alloys as metallic matrix the carbon content is of particular significance, as not only ...

Several experimental techniques are used for phase identification and microstructure characterization of austempered vermicular cast irons (XRD, SEM, TEM and Mössbauer spectroscopy). Acicular structures were found to be ...

The role of B and Si in the formation of (FeCoCrNi) 100-x-y B x Si y high-entropy metallic glasses is studied. It is found that a content of B between 10 and 20 at% and of Si between 5 and 15 at% is able to produce a ...

Experimental data on the phase sound speed of metallic glasses show anomalies in the terahertz range, reflecting an underlying complex behavior of their phonon dispersion spectrum not yet explained. We determine the phonon ...

Quantum technology is one of the most promising and challenging fields in contemporary science. Quantum computing, quantum cryptography, and more generally quantum information technologies claim that they, in the short ...

In this work we study the structural evolution of Al and Fe based metallic glass compositions. The samples were obtained as ribbons by melt-spinning, their glass stability and crystallization were analyzed by calorimetry ...

Fe68.45Pd28.21Co1.66Ni1.66 alloy in ribbon geometry was produced by melt spinning. The microstructure of the samples was examined using scanning electron microscopy. The structural identification of the as-spun ribbon ...
