The Development of FeBe5 Fiber Using a Dual Plasma Deposition System

Abstract:

New fibers are needed to produce intermetallic composites for use in aero and space
propulsion systems because existing fibers do not have adequate thermochemical stability
in desirable structural materials such as iron aluminide. FeBe5 has been predicted
to have thermochemical stability in iron aluminide and would be a desirable reinforcement
if it could be produced in a fibrous form with high strength. A new dual plasma process
has been developed that has the ability to deposit FeBe5 and other difficult-to-deposit
materials at high deposition rates. The dual plasma process will be utilized to develop
the deposition of FeBe5 into oxide fiber substrate producing fiber diameters up to
75u. The FeBe5 fibers will be characterized for mechanical properties and compatibility
in an iron aluminide matrix.
Iron beryllide fibers, predicted to be thermochemically stable in iron aluminide,
other intermetallics, and metals, could be applied in composites for a wide variety
of aero and space propulsion systems and aerospace structures as well as tools, dies
and general structures.
