一种液态模锻高强韧铝合金及其液态模锻方法
摘要：
一种液态模锻高强韧铝合金及其液态模锻方法，其成分及质量百分比为：Si 6.5～7.5%，Mg 0.25～0.35%，Cu 0.05～0.15%，Mn 0.05～0.1%，Ni 0.025～0.05%，Ti 0.005～0.01%，C 0.001～0.002%，Re 0.01～0.03%，Fe ≤0.2%，余量为Al和不可避免的其它杂质元素。液态模锻方法包括配料、熔炼铝合金液、精炼除气除渣、液态模锻成形和固溶时效处理。本发明液态模锻铝合金具有强度高、塑性好的优点，适合于液态模锻汽车受力结构件，如铝合金车轮、转向节、减震塔、悬挂支架、气囊支撑臂、控制臂、制动器卡钳等。
摘要（英）：

Provided are a liquid die forging high-strength and high-toughness aluminum alloy and a liquid die forging method thereof. The liquid die forging high-strength and high-toughness aluminum alloy comprises, by mass, 6.5-7.5% of Si, 0.25-0.35% of Mg, 0.05-0.15% of Cu, 0.05-0.1% of Mn, 0.025-0.05% of Ni, 0.005-0.01% of Ti, 0.001-0.002% of C, 0.01-0.03% of Re, less than or equal to 0.2% of Fe, and thebalance Al and other inevitable impurity elements. The liquid die forging method comprises the steps of proportioning, melting of the liquid aluminum alloy, refining for degassing and deslagging, liquid die forging formation and solution and aging treatment. The liquid die forging aluminum alloy has the advantages of high strength and good plasticity and is suitable for liquid die forging of automobile stress structural components such as aluminum alloy wheels, steering knuckles, damping towers, suspension supports, air bag supporting booms, control arms and brake calipers.
