RETAINER |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a lightweight and strong magnesium alloy retainer. <P>SOLUTION: The retainer 14 comprises a magnesium alloy such as AZ91D and is molded by injection molding. A converging region including a void formed by converging the magnesium alloy in the injection molding flows out of the retainer 14. When the cross-section of the retainer 14 is observed, an α phase having a particle diameter of 20 μm or more constitutes less than 15% in the magnesium alloy constructing the retainer 14. <P>COPYRIGHT: (C)2012,JPO&INPIT |
