Abstract
A wire includes a first wire segment having an end portion and a second wire segment having an end portion. A coupling segment is adjacent the end portions of the first and second wire segments. The coupling segment is configured with a plurality of indents penetrating into at least one of the first and second wire segments.
Claims15
A wire comprising:
- a first wire segment having an end portion;
- a second wire segment having an end portion, one of the first and second wire segments comprising a first material;
- and
- a coupling segment comprising a second material and adjacent the end portions of the first and second wire segments, and wherein the coupling segment is configured with at least one indent penetrating into at least one of the first and second wire segments, wherein the indent comprises a mixture of the first material from the first or second wire segment and the second material from the coupling segment, and wherein the mixture of the first material from the first or second wire segment and the second material from the coupling segment is such that no more than 30 percent of the materials in the indents are brittle intermetallic phases.

A wire comprising:
- a first wire segment having an end portion;
- a second wire segment having an end portion, one of the first and second wire segments comprising a first material;
- and
- a coupling segment comprising a second material and adjacent the end portions of the first and second wire segments, and wherein the coupling segment is configured with at least one indent penetrating into at least one of the first and second wire segments, wherein the indent comprises a mixture of the first material from the first or second wire segment and the second material from the coupling segment, wherein the coupling segment is a tubular coupler separate from the first and second wire segments into which the first and second wire segments are inserted, wherein the first wire segment has a first outer diameter away from the end portion and a second outer diameter adjacent the end portion, the first outer diameter greater than the second outer diameter, wherein the second wire segment has a first outer diameter away from the end portion and a second outer diameter adjacent the end portion, the first outer diameter greater than the second outer diameter, and wherein the tubular coupler has an outer diameter substantially equal to the first outer diameters of the first and second wire segments.
