Composite Aluminum Conductors for Pulsed Power Applications at Hydrogen Temperatures.

摘要

The results of a successful feasibility study on fabricating composite aluminum conductors with low electrical resistance at liquid hydrogen temperatures are reported. The conductors contain fine high-purity aluminum filaments embedded in an Al-Fe-Ce alloy matrix. The lightweight, high strength alloy, with favorable thermal and electrical properties, has its workability compatible to that of pure aluminum. Meanwhile, no Fe/Ce diffusion from the matrix to the aluminum filaments occurs during processing.
