ISS Science for Everyone

Science Objectives for Everyone
The MULTIPHAS experiments focus on the investigation of a sequence of phase transitions with increasing undercooling: from eutectic and dendritic solidification, to spinodal decomposition (a rapid unmixing of a mixture) and glass formation. The kinetics of solidifying samples are obtained from High Speed Camera videos. Microstructure investigation of solidified and frozen samples are performed during post-flight analysis on the ground.

Applications

Space Applications
These new Electromagnetic Levitator (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 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.
 
Two out of 23 samples in Sample Container are used for the experiment:
  1. Cu46Zr54 (ID#26) (Sample sharing with THERMOLAB and NASA QUASI project)
  2. Cu50Zr50 (ID#27) (Sample sharing with THERMOLAB and NASA QUASI 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 40 melting cycles per sample.
Samples to be returned:
  1. Cu46Zr54
  2. Cu50Zr50.
