Metalcasting is rocket science.[ILLUSTRATION OMITTED] A metalcasting experiment, in which an astronaut astronaut, crew member on a U.S. manned spaceflight mission; the Soviet term is cosmonaut. Candidates for manned spaceflight are carefully screened to meet the highest physical and mental standards, and they undergo rigorous training. will melt and re-solidify an aluminum ingot ingot Mass of metal cast into a size and shape such as a bar, plate, or sheet convenient to store, transport, and work into a semifinished or finished product. The term also refers to a mold in which metal is so cast. to investigate solidification in microgravity mi·cro·grav·i·ty n. 1. An environment in which there is very little net gravitational force, as of a free-falling object, an orbit, or interstellar space. 2. , is scheduled to take place aboard the International Space Station's Materials Sciences materials science Study of the properties of solid materials and how those properties are determined by the material's composition and structure, both macroscopic and microscopic. Laboratory early next year. The investigation aims to improve the understanding of the solidification process to validate the predictions of numerical solidification models so that the manufacturing industry can learn more about the casting process and further tailor metallic alloys for life on Earth. |
