ISS Science for Everyone

Science Objectives for Everyone
The PARSEC experiments are focused on the influence of melt convection on phase selection in technically important peritectic alloys- alloys where a solid and liquid phase combine to for a second solid phase at a particular temperature and composition. Different levels of electromagnetically induced convection are applied in order to study the effect of fluid flow on growth kinetics, the incubation time between the formation of the metastable intermediate, and the stable phase. The viscosity is measured in order to obtain input data for the modelling of fluid flow.

Space Applications
Industry partners to the projects are seeking to optimize ground processes, and have a direct interest in the knowledge that is gained from the experiments. This can, in turn, find its way into the development of new light-weight, high-performance structural materials for space applications.

Earth Applications
Investigations carried out with the Electromagnetic Levitator (EML) provide both reference data on thermophysical properties and microstructure formation for the same metallic alloy samples. (The microstructure in an alloy influences its characteristic properties such as strength, flexibility and resistance to fatigue.) This information is of importance for feeding accurate data into current numerical models on one side, and also testing these models aiming to predict the solidification profile and related microstructure formation in the alloy samples. This concerns structural steels, magnetic materials, intermetallic materials, glass forming metallic alloys etc.

Operational Requirements and Protocols

The 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 Sample Container used for experiment:
  • Fe60Co40 (ID#40) (Sample sharing with MAGNEPHAS and ELFSTONE project).
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 35 melting cycles per sample.
  • Samples to be returned: Fe60Co40.
