| titleOfInvention | Super-strong high-conductivity copper alloy used as material for contact line of high-speed railway allowing speed higher than 400 kilometers per hour |
| abstract | A super-strong high-conductivity copper alloy used as a material of a contact line of a high-speed railway allowing a speed higher than 400 kilometers per hour. The copper alloy comprises the following components according to percentages by weight: 3% to 20% of niobium, 0.01% to 1% of chromium, 0.01% to 0.5% of zirconium, 0.01% to 0.2% of titanium, and the balance copper. The copper alloy is in a long bar or line form, niobium in the form of nanofibers and solid solution atoms is distributed in a copper substrate, most of the niobium nanofibers are arranged in the copper substrate approximately in parallel, and the axial direction of the fibers is approximately parallel to the axial direction of copper alloy rods or lines. Chromium in the form of nano-particles and solid solution atoms is distributed around the niobium nanofibers and in the copper substrate, zirconium in the form of copper-zirconium compound nano-particles and solid solution atoms is distributed around the niobium nanofibers and in the copper substrate, and titanium in the form of a copper-titanium GP zone and solid solution atoms is distributed in the copper substrate. The total quantity of niobium, chromium and zirconium solid solution atoms in the copper alloy is smaller than 0.2%. Part of the chromium nano-particles and the copper-zirconium compound nano-particles are pinned in the phase interface of the niobium nanofibers and the copper substrate. |
