Symposium Materials Research in Reduced Gravity
Presentation Title An Overview of a Proposed NASA Flight Experiment on W-heavy Glass-forming Alloy Composites
Author(s) Douglas C. Hofmann, Scott Roberts
On-Site Speaker (Planned) Douglas C. Hofmann
Abstract Scope NASA JPL and MSFC have been developing a flight experiment for the Materials Science Research Rack on the International Space Station to perform diffusion experiments on W-heavy bulk metallic glass-forming alloys. This work will discuss the proposed flight samples, show the experimental setup, and ground-based experiments to demonstrate why microgravity experiments are of interest in this alloy system. The objective will be to understand how gravity affects W diffusion in these alloys and to test wear properties of the alloys once returned from orbit.
