摘要 |
<p>Magnesium alloys containing: Y: 2.0-6.0% by weight Nd: 0-4.0% by weight Gd: 0-5.5% by weight Dy: 0-5.5% by weight Er: 0-5.5% by weight Zr: 0.05-1.0% by weight Zn+Mn: <0.11% by weight, optionally other rare earths and heavy rare earths, the balance being magnesium and incidental impurities and the total content of Gd, Dy and Er is in the range of 0.3-12% by weight, wherein either the alloy contains low amounts of Yb and Sm and exhibits a corrosion rate as measured according to ASTM B117 of less than 30 Mpy, and/or the area percentage of any precipitated particles arising when the alloy is processed having an average particle size greater than 1 m and less than 15 m is less than 3%.</p> |
