Method for producing metal fibers

A method of producing metal fibers, comprising:

• melting a mixture of at least niobium and copper;
• cooling the mixture to form a bulk matrix comprising at least a fiber phase comprising a significant portion of the niobium and a matrix phase comprising a significant portion of the copper;
• and
• removing at least a substantial portion of the matrix phase from the fiber phase;
• wherein at least one of a morphology, a size, and an aspect ratio of fiber in the fiber phase is modified by adjusting at least one process parameter.

A method of producing metal fibers, comprising:

• melting a mixture of at least a fiber metal and a matrix metal;
• cooling the mixture to form a bulk matrix comprising at least a fiber phase and a matrix phase;
• removing at least a substantial portion of the matrix phase from the fiber phase;
• and
• processing the fiber phase, wherein processing the fiber phase comprises at least one of sintering the fiber phase, pressing the fiber phase, washing the fiber phase, rendering the fiber phase into a powder-like consistency, and shortening the fibers of fiber phase.
