ISS Science for Everyone

Science Objectives for Everyone
The RESISTIVITY experiments are used to calibrate and validate the Sample Coupling Electronic (SCE) device, and to obtain first data on electrical resistivity of Niobium-Nickel (NbNi) and Zirconium-Nickel (ZrNi). Various other experiments listed above make use of the SCE device in order to obtain additional information on their materials.

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.
Two out of 23 samples in the Sample Container are used for the experiment:
  1. Zr64Ni36 (ID#36) (Sample sharing with SEMITHERM and NASA QUASI project)
  2. Nb40.5Ni59.5 (ID#37) (Sample sharing with SEMITHERM 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 15 melting cycles per sample.
Samples to be returned:
  1. Zr64Ni36
  2. Nb40.5Ni59.5.
