Embodiment 1
[0021] A method for preparing casting materials applied to nuclear power and wind power, comprising the following steps:
[0022] 1), according to the ratio of aluminum: 6%, iron: 2.5%, manganese: 0.6%, nickel: 10.8%, zinc: 0.8%, copper: the mass percentage of the balance, configure the raw materials, and put them in the power frequency electric furnace , heated to 1150 degrees and completely melted and kept warm;
[0023] 2) Add the rare earth element lanthanum or cerium: 0.09%, by mass percentage, into the alloy solution being kept warm, turn on the vibrating device and the stirring device, the vibration frequency of the vibrating device is 15 times / second, and the stirring rate of the stirring device is : 150 rpm, stirring time: 10-15 minutes;
[0024] 3) Add 9.5% titanium carbide with a particle size of less than 50 microns to the alloy solution by mass percentage, and stir again at the same time, the stirring rate is 350 rpm, and the stirring time is 10 to 15 minutes;

Embodiment 2
[0031] Embodiment 2 is different from Embodiment 1 only in the ratio of raw materials, and is the same in other respects. Therefore, only the differences will be described below.
[0032] The percentage of each component in step 1) is: aluminum: 6.5%, iron: 3%, manganese: 0.9%, nickel: 11.2%, zinc: 1.2%, copper: balance.
[0033] The mass percentage of the rare earth element lanthanum or cerium in step 2) is: 0.1%.
[0034] The mass percentage of titanium carbide in step 3) is: 10%.
[0035] According to the second embodiment, basically the same effect as that of the first embodiment can be achieved.
Embodiment 3
[0037] Embodiment 3 is different from Embodiment 1 and 2 only in the ratio of raw materials, and is the same in other respects. Therefore, only the differences will be described below.
[0038] The percentage of each component in step 1) is: aluminum: 6.8%, iron: 3.5%, manganese: 1.1%, nickel: 11.8%, zinc: 1.8%, copper: balance.
[0039] The mass percentage of the rare earth element lanthanum or cerium in step 2) is: 0.18%.
[0040] The mass percentage of titanium carbide in step 3) is: 10.5%.
[0041] According to the third embodiment, basically the same effects as those of the first and second embodiments can be achieved.
[0042] Material experiment data performance comparison table:
[0043]
[0044] It can be known from the above table that the hardness of the material is improved and the porosity of the material is reduced through the cast material of the present invention.
