Electromagnetic Levitator Batch 2 - Thermophysical Properties and Solidification Behaviour of Undercooled Ti-Zr-Ni Liquids Showing an Icosahedral Short-range Order (EML Batch 2 - ICOPROSOL) - 01.31.17

ISS Science for Everyone

Science Objectives for Everyone
ICOPROSOL experiments are focused on measurements of the thermophysical properties of supercooled Titanium-Zirconium-Nickel (Ti-Zr-Ni) liquids of different composition, which are to be correlated with terrestrial x-ray liquid structure studies. A second focus is an evaluation of a new model for nucleation that takes into account long-range diffusion and interfacial attachment; this is tested by studying the effect of fluid flow on maximum undercooling. Measurements of the dendritic growth velocity and viscosity are made to obtain input data for modelling and data analysis.

Applications

Space Applications
These new EML investigations have the potential to impact how scientists develop lighter, higher-performing alloys for use both on Earth and in space travel.

Earth Applications
Materials science is an integral part of development of new materials for everyday life here on Earth. The goal of studying materials processing in space is to develop a better understanding of the chemical and physical mechanisms involved. Materials science research benefits from the microgravity environment of space, where the researcher can belter isolate chemical and thermal properties of materials from the effects of gravity. With this knowledge, reliable predictions can be made about the conditions required on Earth to achieve improved materials.

Operations

Operational Requirements and Protocols

The Electromagnetic Levitator (EML) is used, consisting of: Experiment Module, Experiment Control Electronics and High-Speed Camera Operating System, Levitation Power Supply and Water Cooling Module, Gas Supply Module, and Sample Chamber.
 
One out of 23 samples in the Sample Container are used for the experiment: Ti39.5Zr39.5Ni21 (ID#39) (sample sharing with THERMOLAB, PARSEC, and NASA QUASI and ELFSTONE projects).
 
After container installation by crew, all activities are fully commanded by the ground. Sample processing is executed during the crew sleep period, with continuous Ku and S band communications coverage so that micro-g-level and vibrations are known.
 
General: 1 run per sample with 12 melting cycles per sample.  Samples to be returned: Ti39.5Zr39.5Ni21.
