UA to Slice Metallic Space 'Bologna'
UA researchers aim to find out how metal microstructures form in zero gravity.
University of Arizona researchers eagerly await the arrival of a small cylinder of aluminum silicon alloy that was melted and resolidified in the zero gravity of a metals lab on the International Space Station.
They plan to "slice it like a bologna and examine it from one end to the other," said David Poirier, a UA professor of materials science and engineering.
Poirier and his team expect to see a more perfect version of the alloy than can be created on Earth.
