o:3922 Influence of thermo-mechanical processing parameters on the tensile strength of copper wire produced by the “up cast” process en Abstract: Copper wire with a starting diameter of Ø 8mm, produced by the "up cast" process, was used in this work. The obtained wire is subjected to drawing, whereby the profiled wires with the following dimensions are obtained: 2.5 x 1.8 mm (deformation degree ε=91 %), 2 x 1.25 mm (deformation degreeε=95 %) and 2.74 x 0.41 mm (deformation degree ε=99 %). 30 cm long samples were cut from each cross section, which were first annealed, then cooled in water and finally subjected to the tensile strength measurement. The annealing was carried out in a nitrogen atmosphere of very high purity at temperatures of 400, 500 and 600 ºC for 2 times, 4 times and 6 times, the time for which a semirecrystallized structure is obtained. For greater accuracy of the results, three repetitions of the experiment were performed. An increase in tensile strength is observed at all annealing times with an increase in deformation degree. Keywords: “up cast” postprocess, profiled copper wires, tensile strength. 91552100 136622345 1552100 978-86-7827-052-9 2024-02-02T12:21:21.205Z 44 no 46 Milijana Mitrović Tehnički fakultet u Boru 0000-0001-7478-2453 Saša Marjanović Tehnički fakultet u Boru person 0000-0001-6930-2232 Biserka Trumić Institut za rudarstvo i metalurgiju Bor person 0000-0001-8328-7315 Jasmina Petrović Tehnički fakultet u Boru person 0000-0002-9131-339X Emina Požega Institut za rudarstvo i metalurgiju Bor person 0000-0001-6797-2435 Miloš Janošević Institut za rudarstvo i metalurgiju Bor person 0000-0002-0818-1235 application/pdf 1614923 https://unilib.phaidrabg.rs/o:3922 no yes 1 70 92000004 71A03 Proceedings: International October Conference on Mining and Metallurgy (53 ; 2022 ; Bor) 155 160 2022
