Embodiment 1
[0029] (FeCoNiCrAlCu) provided by the present invention p / 2024A1 A method for regulating the interface structure of composite materials, including the following steps:
[0030] Iron powder, cobalt powder, nickel powder, chromium powder, aluminum powder, copper powder and other powders with a purity of 99.9% are mixed according to an equiatomic ratio, placed in a ball mill tank, vacuumed and argon gas is introduced, and then high-energy High-entropy alloy powders were prepared by ball milling and mechanical alloying. Mix the high-entropy alloy powder and 2024Al powder according to the addition amount of the reinforcing phase at 10wt.%, to obtain a composite material powder, and then carry out cold isostatic pressing at a pressure of 250 MPa for 2 minutes, and the block after cold isostatic pressing Perform microwave sintering at 480°C for 40 minutes to make (FeCoNiCrAlCu) with interface regulation and heat treatment p / 2024A1 composite material base material
[0031] First,...
Embodiment 2
[0035] Iron powder, cobalt powder, nickel powder, chromium powder, aluminum powder, copper powder and other powders with a purity of 99.9% are mixed according to an equiatomic ratio, placed in a ball mill tank, vacuumed and argon gas is introduced, and then high-energy High-entropy alloy powders were prepared by ball milling and mechanical alloying. Mix the high-entropy alloy powder and 2024Al powder according to the addition amount of the reinforcing phase at 15wt.%, to obtain a composite material powder, and then carry out cold isostatic pressing at a pressure of 250 MPa for 2 minutes, and the block after cold isostatic pressing Perform microwave sintering at 480°C for 40 minutes to produce (FeCoNiCrAlCu) p / 2024A1 composite base material.
[0036] First, the prepared (FeCoNiCrAlCu) p / 2024A1 Composite material base material is placed in WBMW-X4 microwave sintering furnace for solid solution treatment. Vacuumize the furnace and fill it with nitrogen, heat at 45°C / min to 30...
Embodiment 3
[0040] Iron powder, cobalt powder, nickel powder, chromium powder, aluminum powder, copper powder and other powders with a purity of 99.9% are mixed according to an equiatomic ratio, placed in a ball mill tank, vacuumed and argon gas is introduced, and then high-energy High-entropy alloy powders were prepared by ball milling and mechanical alloying. Mix the high-entropy alloy powder and 2024Al powder according to the addition amount of the reinforcing phase at 20wt.%, to obtain a composite material powder, and then perform cold isostatic pressing at a pressure of 250 MPa for 2 minutes, and the block after cold isostatic pressing Perform microwave sintering at 480°C for 40 minutes to produce (FeCoNiCrAlCu) p / 2024A1 Composite material parent material;
[0041] The prepared (FeCoNiCrAlCu) p / 2024A1 Composite material base material is put into WBMW-X4 microwave sintering furnace, vacuumize the furnace and fill it with nitrogen, heat at 50°C / min to 300°C for 4 minutes, then rapi...
