Comparison of Hot Forging Characteristics of Mg Alloys

Mg합금의 열간단조 특성 비교

Mg alloys have the highest specific strength which can be used industrial application. Since formability of Mg alloys is very limited, optimization of forming process is always needed for successful engineering application. In the present study. three different Mg alloys were used for hot forging processes and several process variables such as temperature and forging speed were investigated to improve forgeability of Mg alloys. To understand the effect of process variables in details, 2D-finite element analysis and forging experiment was performed. In the results, forging speed seems to be more important than forging temperature in hot forging of Mg alloys.
