Experiment Description

Research Overview
The MAGNEPHAS experiment uses the Electromagnetic Levitator’s high-speed camera to observe magnetic alloys such as iron (FE), cobalt (Co), and nickel (Ni). Of particular interest for this experiment is the instant when a material reaches a new state, such as liquid or solid.

Applications

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.

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.
 
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.
 
One run per sample, with 25 melting cycles.
 
One out of 23 samples in Sample Container used for experiment:
  1. Fe90B10 (ID#29) (Sample sharing with PARSEC, THERMOLAB and NASA ELFSTONE projects).
