Changes in Microstructure, Mechanical Properties, and Electrical Conductivity of Severely Drawn AA1070 Wire with Annealing
Sang-Hyeon Jo, Seong-Hee Lee
Korean J. Met. Mater. 2024;62(10):749-756.   Published online 2024 Oct 5
DOI: https://doi.org/10.3365/KJMM.2024.62.10.749

Abstract
The drawing process severely deforms commercial AA1070 alloy for electrical wire, reducing a rod from a diameter of 2.0 mm to 0.4 mm, followed by annealing. The annealing process was conducted at various temperatures ranging from 200℃ to 450℃, with each temperature maintained for 1hour. The effects of increasing annealing..... More

                
Changes in Microstructure, Mechanical and Electrical Properties with Progress of Cold Wire-Drawing for AA1070
Sang-Hyeon Jo, Seong-Hee Lee
Korean J. Met. Mater. 2023;61(11):867-873.   Published online 2023 Oct 29
DOI: https://doi.org/10.3365/KJMM.2023.61.11.867

Abstract
Commercial AA1070 alloy for electrical wire is severely deformed by the drawing process when a rod with a diameter of 2 mm is greatly reduced to 0.4 mm by multi-pass. Changes in the microstructure, mechanical properties, and electrical properties of the Al alloy during the wire-drawing process were investigated in..... More

Effect of Shear Deformation During Drawing on Inhomogeneous Microstructures and Textures in High Purity Copper Wires After Annealing
고순도 구리 선재의 어닐링 후 불균질 미세조직과 집합조직에 미치는 신선 시 전단 변형의 영향
Hyun Park, Sang-Hyeok Kim, Se-Jong Kim, Hyo-Jong Lee
박현, 김상혁, 김세종, 이효종
Korean J. Met. Mater. 2018;56(12):861-869.   Published online 2018 Dec 5
DOI: https://doi.org/10.3365/KJMM.2018.56.12.861

Abstract
To determine the origin of the inhomogeneous microstructure and texture observed in drawn and annealed high purity copper wires, two kinds of drawing process conditions and their influence was investigated. The regular condition, based on a symmetric die, and a condition designed intentionally to produce an inhomogeneous shear deformation using..... More
