Low temperature underaging of lithium bearing alloys. |
| 摘要 |
<p>The combination of strength and fracture toughness properties of aluminum-lithium alloys are significantly enhanced by underaging the alloys at temperatures ranging from 200 DEG F to below 300 DEG F for relatively long periods of time.</p> |
