Embodiment 1
[0044] Taking the preparation of a nickel-aluminum-based multiphase alloy with a component content of 30% nickel and 70% aluminum as an example, the following steps are included:
[0045] (1) Mold loading: Assemble a metal mold with a diameter of 5mm and a length of 5mm in the negative pressure suction casting system in the vacuum electric arc furnace;
[0046] (2) Sample loading: start the vacuum electric arc furnace, put high-purity Ni and high-purity Al (>99.9wt.%) with a nominal composition of 70Al-30Ni into the crucible of the vacuum electric arc furnace;
[0047] (3) Vacuuming: Open the vacuum valve and vacuumize until the vacuum degree is 2.0×10 -3 MPa, then tighten the vacuum valve;
[0048] (4) Gas filling: Pour argon gas into the sample chamber of the vacuum electric arc furnace until the vacuum degree is 0.5MPa;
[0049] (5) Repeat steps 3 to 4;
[0050] (6) The vacuum electric arc furnace is energized to melt Ni and Al, and continues to heat until the metal is m...
Embodiment 2
[0056] The difference between this embodiment and embodiment 1 is that the component content in the nickel-aluminum base multiphase alloy is 65% nickel and 35% aluminum, and the vacuum degree in step 3 is 5.0×10 -3 MPa, in step 4 and step 8, argon gas is flushed until the vacuum degree is 0.65MPa, in step 6, the heating temperature is 1620°C, in step 7, keep warm for 2 minutes, the output current of magnetic stirring is 15A, and suction cast into a regular block of φ15mm×15mm body.
[0057] The microstructure and phase analysis of the nickel-aluminum-based multiphase alloy prepared in this example are consistent with the results of Example 1, and will not be repeated here.
Embodiment 3
[0059] The difference between this embodiment and embodiment 1 is that the component content in the nickel-aluminum base multiphase alloy is 67% nickel and 33% aluminum, and the vacuum degree in step 3 is 3.0×10 -3 MPa, in step 4 and step 8, argon gas is flushed until the vacuum degree is 0.55MPa, in step 6, the heating temperature is 1610°C, in step 7, the temperature is kept for 1.5min, the output current of magnetic stirring is 10A, and the suction casting is φ12mm×12mm blocks.
[0060] The microstructure and phase analysis of the nickel-aluminum-based multiphase alloy prepared in this example are consistent with the results of Example 1, and will not be repeated here.
[0061] In summary, the nickel-aluminum-based multiphase alloy is prepared by the present invention, the raw material is not powder, the incidence of safety accidents is reduced, and the surface quality of the nickel-aluminum-based multiphase alloy is good, the size and shape of the block are regular, the co...
