A conductive supporting member includes an outer portion that includes a Cu matrix phase and a second phase dispersed in the Cu matrix phase and containing a Cu—Zr compound and that has an alloy composition represented by Cu-xZr (x is atomic % of Zr and 0.5≤x≤16.7 is satisfied) and an inner portion that is present on an inner side of the outer portion, is formed of a metal containing Cu, and has higher conductivity than the outer portion.

A method for making a porous metal article of manufacture is provided. The method includes subjecting a saturated aqueous electrolytic solution wherein silver or copper is a donor in a container with two electrodes, where dendrite crystals of silver or copper or silver or copper nanowires are formed and collected. The collected dendrite crystals or nanowires are pressed and sintered, thereafter cooled to room temperature at room temperature and finally pressing the cooled geometric shape to form the porous silver metal article of manufacture. The collected dendrites crystals or nanowires also can be pressed in a carbon based mold or, alternatively, a non-carbon based mold and in vacuum, sintered, cooled to room temperature.

A method for densifying a material includes arranging the material in a cavity of a mold and applying pressure to the material in the mold. While applying pressure to the material in the mold, a magnetic field is applied to the material in the mold to cause the material to transform between a first allotrope phase and a second allotrope phase. Applying the magnetic field to the material includes magnetic cycling, which includes one or more iterations of adjusting the magnetic field to a first strength, and then adjusting the magnetic field to a second strength. The method includes determining a density of the material during the magnetic cycling and, responsive to determination that the determined density reaches a threshold density, stopping the magnetic cycling.
