| Research Abstract |
Magnesium alloys are receiving a lot of attention in various industries because of an increasing demand for lightweight materials. However their deformation behavior has not been understood well. The present study aims at investigating the cyclic tension-compression behavior in magnesium alloy sheets both experimentally and theoretically. The experimental results under various loading conditions showed that the activity of twinning played a significant role in the work-hardening behavior. Based on the results obtained from the experiment, a new theoretical model was proposed to predict the deformation behavior based on the crystalline deformation. The simulation predicted the work-hardening behavior as well as the evolution of texture accurately, verifying the model. The above results brought new insight into the deformation behavior of magnesium alloy sheets.
