| Abstract Scope |
Bulk metallic glasses are a new development of metallic materials with superior properties, such as high elastic limits and high hardness. This makes the materials interesting for applications, e. g. in space exploration.
Study of glass formation is also the study of the opposite, crystal nucleation – which is influenced by kinetic and thermodynamic driving forces. As such, thermophysical properties (viscosity, specific heat capacity) and the derived thermodynamic functions are important in understanding of glass formation.
Within the last few years, several BMG materials were investigated in the ISS-EML. The two Zr-based glasses Vit106a (Zr58.5Cu15.6Ni12.8Al10.3Nb2.8) and LM105 (Zr52.5Cu17.9Ni14.6Ti5Al10) as well as a Fe-based glass former (Fe57.75Ni19.25Mo10.0C5.0B8.0) were processed successfully in the Material Science Laboratory Electromagnetic Levitator (ISS-EML) on board the European Space Laboratory Columbus in the international space station (ISS).
We will present an overview over the thermophysical properties of these bulk metallic glasses. |
