Embodiment 1
[0064] In the method for preparing a high-strength and high-toughness multi-component Al-Cu alloy provided in this example, the raw material is heated into a molten state, and then sprayed by an aluminum alloy spray forming equipment to form a multi-component Al-Cu alloy. The multi-component Al-Cu alloy is composed of Al , Cu, Mn, Ni, V, Sc and impurity Si, Fe elements. It consists of the following alloy components in mass percentage: as shown in Table 1. Pure aluminum, Al-40Cu, Al-30Mn, Al-10Ni, Al-5V and Al-5Sc master alloys are used as raw materials, and the sum of all the above alloy components is 100%.
[0065] Specifically include the following steps:
[0066] S1. Take pure aluminum with a purity of 99.98% and place it in a smelting furnace, and heat it at 800°C until all of it becomes molten;
[0067] S2. Add Al-40Cu, Al-30Mn, Al-10Ni, Al-5V and Al-5Sc master alloys in sequence, lower the temperature to 720°C, stir thoroughly, and let stand for 15-25min; The method o...

[0071] In the method for preparing a high-strength and high-toughness multi-component Al-Cu alloy provided in this example, the raw material is heated into a molten state, and then sprayed by an aluminum alloy spray forming equipment to form a multi-component Al-Cu alloy. The multi-component Al-Cu alloy is composed of Al , Cu, Mn, Ni, V, Sc and impurity Si, Fe elements. It consists of the following alloy components in mass percentage: as shown in Table 1. Pure aluminum, Al-40Cu, Al-30Mn, Al-10Ni, Al-5V and Al-5Sc master alloys are used as raw materials, and the sum of all the above alloy components is 100%.
[0072] The specific production steps are the same as in Example 1, except that the melting temperature in step S1 is 820°C, and in step S2, the temperature of the master alloy is lowered to 700°C, and then the anhydrous The method of high-purity nitrogen to remove slag, the time is 60min; the rest of the steps are the same as in Example 1. Prepare the deposition blank o...
