MAGNESIUM ALLOY MATERIAL |
| 摘要 |
A magnesium alloy material having high corrosion resistance is provided. The magnesium alloy material contains a magnesium alloy containing 7.3% to 16% by mass Al, wherein a region having an Al content of 0.8x % by mass or more and 1.2x % by mass or less occupies 50% by area or more, a region having an Al content of 1.4x % by mass or more occupies 17.5% by area or less, wherein x % by mass denotes the Al content of the entire magnesium alloy material, and there is substantially no region having an Al content of 4.2% by mass or less. The magnesium alloy material has small variations in Al concentration and includes a few regions having a very low Al content, thereby effectively preventing and retarding local corrosion. Thus, the magnesium alloy material has higher corrosion resistance than die-cast components having the same Al content. |

1. A magnesium alloy material, comprising a magnesium alloy that contains 7.3% by mass or more and 16% by mass or less Al and has a surface, wherein
a region having an Al content of (x×0.8)% by mass or more and (x×1.2)% by mass or less occupies 50% by area or more in the surface, a region having an Al content of (x×1.4)% by mass or more occupies 17.5% by area or less in the surface, wherein x % by mass denotes the Al content of the entire magnesium alloy material, and
there is substantially no region having an Al content of 4.2% by mass or less. |
