Abstract
Magnesium alloys have been in the spotlight due to their high specific strength and stiffness. In order to manufacture forged products with magnesium alloys, it is crucial to determine the dependence of the formability on processing conditions. In this study, the formability of ZK60A manufactured by a continuous casting was experimentally investigated by uniaxial compression and backward extrusion. Processing parameters such as temperature and compressing speed varied in experiments. The surface quality and internal defects of the deformed specimens were carefully inspected for comparison purposes. A damage criterion is employed to quantify the formability under these two different testing routes. Furthermore, our results were compared to the damage data of the similar material reported in the literature.
