Development of rolling technology for twin roll casted 1500MM wide magnesium AZ31 alloy

Abstract

Magnesium alloy AZ31 sheets of 4.5-6.5mm thick and 1500mm width were produced by twin roll strip casting first time in Turkey. Afterwards, sheets were hot and cold rolled down to less than 1mm both by laboratory and industrial scale rolls. Microstructure of the sheet was analyzed by optical microscope and transmission electron microscope. In addition, pole figures have been obtained by XRD studies. Mechanical properties were investigated by tensile tests and also hardness measurements. Annealing heat treatments were performed on the produced sheets.
