| Abstract Scope |
Bulk metallic glasses are advanced materials with several superior properties, such as extremely high elastic limit and high hardness, making them interesting materials for a number of applications.
For the development of process simulations and for the calculation of thermodynamic functions, describing crystal nucleation and its absence – glass formation, knowledge of thermophysical properties in the solid and liquid phase are necessary. New processes, such as 3D-printing, can easily achieve the critical cooling rate, and hence one of the limits for production of large glassy parts can be overcome.
During the last years, a number of BMG materials were investigated in the electromagnetic levitator ISS-EML on board the international space station. That way, a number of thermophysical properties (surface tension, viscosity, specific heat, total hemispherical emissivity) were determined for these samples.
We give an overview over the ISS-EML capabilities and the thermophysical properties measured for some bulk metallic glasses. |
