BSTRACTMechanical alloying has been repeatedly demonstrated as an effective means to create unique structural materials

but it is comparatively rare that functional alloys are produced. Multi-phase functional alloy production is demonstrated with an oxide-dispersed Ni–Cu catalyst. These catalyst particles are designed to form porosity and catalyze carbon nanofiber deposition

in situ

which results in a six-fold increase in deposition rate over traditional preparation methods. This technique serves as a template for many other systems possible with MA.
