| titleOfInvention | Preparation method of high-toughness aluminum alloy sheet material for aviation and spaceflight |
| abstract | The invention discloses a preparation method of a high-toughness aluminum alloy sheet material for aviation and spaceflight. The high-toughness aluminum alloy sheet material comprises, by mass, 4.8-5.5% of Zn, 1.6-2.4% of Mg, 1.2-1.8% of Cu, 0.8-1.4% of Li, 0.3-0.7% of Mn, 0.05-0.1% of Si, 0.15-0.25% of Fe, 0.3-0.5% of Co, 0.2-0.3% of Ti, 0.15-0.25% of V, 0.1-0.2% of Zr, 0.05-0.15% of Bi, 0.04-0.08% of B, 0.03-0.05% of Ce, 0.02-0.03% of Y, 0.01-0.02% of Er and the balance Al. Through reasonable adjustment of a component ratio and heat treatment processes, aluminum alloy density is reduced, aluminum alloy mechanical strength is improved, excellent toughness and heat stability and excellent comprehensive properties are kept, and aluminum-lithium alloy density, toughness and heat stability are guaranteed. The preparation method has simple processes, a low cost and high efficiency, can be controlled easily, and can realize automatic large-scale production. The aluminum alloy can be widely used in materials for aviation and spaceflight industry. |
