title = "Analysis of Creep Behavior of Magnesium Alloy Sheet (AZ31B) in Warm Forming",
abstract = "In this study, creep behavior characteristics of magnesium alloy sheet (AZ31B) according to pre-strain during warm forming were analyzed through experiments. In addition, stress relaxation process was analyzed by applying the creep behavior of magnesium alloy sheet to analytical simulation. In the creep test, the strain due to the creep phenomenon of magnesium alloy at room temperature was 0.001 at 1000 s of constant load holding time, whereas it was broken at 8 s at 250 °C. The stress exponent of magnesium alloy at room temperature is 10.60 and the stress exponent is 4.8 at 250 °C. Similarly, in the case of stress relaxation experiments at room temperature, the amount of load reduction was 74 N at 1000 s while the amount of load reduction was reduced by 522 N at 250 °C. The stress exponent and parameters obtained from the experiments were applied to the analysis simulation, and the creep and stress relaxation processes were compared with the experimental results.",
