Abstract

Within the last year and for the first time worldwide, the innovative twin-roll casting process has been implemented for magnesium wire at the pilot plant at the Institute of Metal Forming of TU Bergakademie Freiberg. The aim of this study is to present a new process route via continuously twin-roll casting AZ31 magnesium alloy wires. Due to the combination of solidification and forming in one process step, in rolling direction deformed grains are present and precipitates are fine distributed. Remarkably, only a short heat treatment after twin-roll casting is necessary to dissolve segregations and to form equiaxed grains. Three states, namely twin-roll cast and two selected heat-treated, are characterized by means of microstructural investigations, texture investigations, tensile tests and hardness measurements.
