[0024] Example 1
[0025] A high-performance high-entropy alloy processing method, the processing method includes the following steps: according to the master alloy (Fe 40.32 Mn 39.66 Co 9.38 Cr 10.64 ) 99-x Mo 1 C x The nominal composition of the compound is mixed and smelted to obtain a cast alloy with a grain size of about 100-500 μm; wherein, 0
[0026] 1) According to the nominal composition (Fe 40.32 Mn 39.66 Co 9.38 Cr 10.64 ) 99.25 Mo 1 C 0.75 The smelting temperature is 1450-1550 degrees Celsius, preferably 1500 degrees Celsius; the melting time is five minutes, and the as-cast alloy with a grain size of about 100 μm is obtained;
[0027] 2) Under this method, a single 100g smelting can ensure the uniformity of composition and structure, and the yield strength of the material is about 413MPa, and the tensile strength is about 774MPa, which meets the service requirements and can be used directly without subsequent treatment;
[0028] The tensile curve of the high-entrop...

[0030] Example 2
[0031] 1) According to the nominal composition (Fe 40.32 Mn 39.66 Co 9.38 Cr 10.64 ) 99 Mo 1 C 1 The total mass is about 100g, and it is smelted in an induction furnace under the protection of argon. The smelting temperature is 1450-1550 degrees Celsius, preferably 1500 degrees Celsius; the melting time is five minutes, and the as-cast state with a grain size of about 100 μm is obtained. alloy;
[0032] 2) Under this method, a single 100g smelting can ensure the uniformity of composition and structure, and the yield strength of the material is about 560MPa, and the tensile strength is about 1024MPa, which meets the service requirements of high-entropy alloys and can be used directly without subsequent processing;
[0033] The tensile curve of the ingot of this composition is as figure 1 In x=1, it can be seen that Fe without carbon Mo and C prepared by the same method 40.32 Mn 39.66 Co 9.38 Cr 10.64 Compared with alloys, the combination of strength and plasticity i...
