o:3923 Hardness of bimetallic strip Cu – Č.4571 after the cold rolling and annealing en Abstract: Samples of bimetallic strip Cu-Č.4571 were cold rolled with different reduction degrees, and the ones deformed with the highest reduction degrees were annealed afterwards at different temperatures for different periods of time. The values of the hardness of the layers of the bimetallic strip were obtained as a function of the degree of deformation, and the annealing temperature. Global flow of curves hardness - total deformation, increases, where this flow, for both curves, can be divided into three parts. A global decrease in hardness was observed with an increase in the annealing temperature, for all periods of time, in both the steel layer and the copper layer. Keywords: bimetallic strip, hardness, deformation degree, annealing. 91552100 136836873 1552100 978-86-7827-052-9 2024-02-02T12:40:30.425Z 44 no 46 Saša Marjanović Tehnički fakultet u Boru 0000-0001-6930-2232 Milijana Mitrović Tehnički fakultet u Boru person 0000-0001-7478-2453 Emina Požega Institut za rudarstvo i metalurgiju Bor person 0000-0001-6797-2435 Biserka Trumić Institut za rudarstvo i metalurgiju Bor person 0000-0001-8328-7315 Miloš Janošević Institut za rudarstvo i metalurgiju Bor person 0000-0002-0818-1235 application/pdf 1282075 https://unilib.phaidrabg.rs/o:3923 no yes 1 70 92000004 71A03 Proceedings: International October Conference on Mining and Metallurgy (53 ; 2022 ; Bor) 161 164 2022
