Research on the influence of the structural state of Cu-ETP wire rod on the annealing susceptibility of wires

摘要

While the chemical composition of wire rod is ultimately modified with oxygen, the structural state depends on the temperature and speed of the rolling and casting process. This paper presents the results of the simultaneous effects of the chemical composition and the structural state of Cu-ETP wire rod on annealing tests such as spiral elongation and the rapid tensile test. It also discusses new propositions for alternative tests which allow for a quick annealing susceptibility rating.
