Impact of the heat treatment parameters on ultimate tensile strength, microstructure and wire drawing process of Zn-Al15

Abstract

Research conducted in the current paper examines the impact of the heat treatment at temperatures from 150 °C to 300 °C with time intervals between 1 and 6 hours on susceptibility to drawing process of Zn-Al15 wire rod manufactured within the industrial continuous casting and rolling line. The mechanical properties studies proved that the heat treatment caused the increase in the ultimate tensile strength values of the alloy whereas the drawing process caused a significant decrease, which suggests that this alloy after the specific heat treatment cannot be subjected to strain hardening.
