Forged aluminum belongs to Al-Mg-Si-Cu series and Al-Cu-Mg-Ni-Fe series alloys. There are many types of alloying elements in forged aluminum, but the content of each element is small, so it has good thermoplasticity and is suitable for manufacturing various aviation forgings, especially large forgings with complex shapes. Mixing copper, magnesium, silicon and other elements with wrought aluminum alloys can form compounds such as Mg2Si, Al2CuMg, and CuAl2. After adding iron and nickel, the service temperature of forged aluminum can be increased, so it is called heat-resistant forged aluminum alloy. Common wrought aluminum alloys include 6A02, 2A50, 2B50, 2A14, etc. The supply state is generally quenching and artificial aging.
For wrought aluminum alloys that need to work under temperature-relieving conditions, a small amount of transition group elements manganese, chromium, germanium, and titanium are often added to dissolve these elements in the matrix, strongly increase the recrystallization temperature, and effectively prevent the second phase dispersion and precipitation. The crystallization process and grain growth. The recrystallization temperature is also an indicator of heat resistance. Too high content of alloying elements in wrought aluminum alloy will cause serious decline in process plasticity and corrosion resistance of wrought aluminum alloy, and even make the pressure processing of wrought aluminum alloy difficult. Therefore, the content of w (Cu) in the deformed aluminum alloy does not exceed 5%, w (Mg) does not exceed 2.5%-5%, w (Zn) does not exceed 3%-8%, and w (Si) does not exceed 0.5%- 1.2%. Elements such as iron and silicon are harmful impurities in forged aluminum alloys. Most wrought aluminum alloys have good forgeability and can be used to produce forgings of various shapes and types. Aluminum satin parts can be produced by various existing forging methods, including free forging, die forging, dry forging, roll forging, rolling, spinning, ring rolling and extrusion. The flow stress of alloys obviously varies with the composition. The maximum flow stress of each alloy is about twice the minimum; some low-strength forged aluminum has a lower flow stress than carbon steel. The flow stress of some other wrought aluminum alloys is very similar to that of carbon steel. As an alloy, wrought aluminum alloy is generally considered to be more difficult to forge than carbon steel and many alloy steels, but compared to nickel, cobalt-based alloys and titanium alloys, forged aluminum alloys are easier to forge, especially when isothermal die forging processes are used. in this way.
