- Abstract
- Magnesium alloys, which have low specific gravities and energy consumption, as needed in recycling, are increasingly drawing attention in the automobile industry. The yield and tensile strengths of existing commercial magnesium alloys do not satisfy the requirements of automobile parts. Recently, high-strength magnesium alloys containing Sn have been developed and applied to automobile parts. In this study, a forgeability test was carried out using Sn-containing magnesium alloys of the Mg-Sn-Al-Zn series, through forward/backward extrusions, which have deformation modes similar to actual automobile parts. The test was conducted at forging temperatures of 523 K and 723 K, and strain rate of 10/s. The forgeability analysis measured the maximum height, hardness, and microstructure of the extruded part. The maximum height of the part was higher at the forging temperature of 723 K than at 523 K; however; the part's hardness was higher at 523 K than at 723 K EBSD was used to analyze the microstructure of the extruded part.
