Description

technical field [0001] The invention belongs to the field of aluminum alloys, in particular to a high-strength and high-toughness aluminum alloy material. Background technique [0002] Aluminum alloy is an extended product of pure aluminum, and the density of pure aluminum is small (ρ=2.7g / m 3 ), which is about 1 / 3 of that of iron, and has a low melting point, about 660°C. Aluminum has a face-centered cubic structure, so it has high plasticity (δ: 32-40%, ψ: 70-90%), so It is easy to process, can be made into various profiles and plates, and has good corrosion resistance. However, the strength of pure aluminum is very low, so it is not suitable for structural materials. Through long-term production practice and scientific experiments, people have gradually strengthened aluminum by adding alloying elements and using heat treatment, which resulted in a series of aluminum alloys. [0003] Casting aluminum alloy, as the name suggests, is based on aluminum, filling the mold in...
