| Abstract Scope |
In this study, spring-back of magnesium alloy sheet in V-bending was observed according to holding time in the die set and plastic deformation at warm forming conditions. Also, the creep behavior of the magnesium alloy sheet was investigated in the numerical simulation to analyze the spring-back. At room temperature, the spring-back is 28.11° and 24.99° at holding time of 0 and 1000sec respectively. Also, at 250°, the spring-back is 11.46° and 1.12° at holding time of 0 and 1000sec respectively. The results indicate that creep recovery occurs by increasing holding time in the die set during the warm forming. The experiment was conducted at different punch radius R(1, 2, 4, 5mm) to analyze the effect of creep recovery velocity on the spring-back during V-bending operation. Furthermore, Microstructure observations were conducted for detail insight into the results. |
