Experiment Description

Research Overview
METCOMP investigates how microgravity affects the metallic structure of a nickel-titanium alloy. When particles come into contact with a liquid they can be pushed away or engulfed by the liquid, like a ball floating on the sea. Depending on the size of an incoming wave, the ball could be pushed forwards like a surfer, or submerged by the water. On an atomic scale, a similar process occurs with metals as they come into contact with other liquid metals. Understanding this process could lead to more exotic metal alloys, or improve existing complex alloys.

Applications

Space Applications
Industry partners to the projects seek 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 Electro-Magnetic 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
After container installation by crew, all activities are fully commanded by ground. Sample processing is executed during crew sleep, with continuous Ku and S band coverage so that micro-g-level and vibrations are known. One run per sample, with several melting cycles. Exact number of melting cycles for this experiment is still to be determined.
Samples to be returned:

  1. Ni96Ta4+Ta2O5
  2. Ni98Ta2+Ta2O5
