專利摘要(中)
Differing from traditional alloys often containing one primary elemental composition, the present invention reforms a conventional superalloy to a high-entropy superalloy by redesigning the elemental compositions of the conventional superalloy based on a mixing entropy formula. Particularly, this high-entropy superalloy shows advantages of light weight and low cost under the premise of containing a low amount of expensive metal composition. The proposed high-entropy superalloy of the present invention comprises a primary elemental composition and at least one principal strengthening elemental composition, wherein the primary elemental composition has a first element content of at least 35 at％ and each of the principal strengthening elemental compositions have a second element content of over 5 at％. Moreover, a variety of experimental results have proved that the high-entropy superalloy simultaneously possesses a variety of excellent high-temperature mechanical properties, such as high mechanical strength, high corrosion resistance, high oxidation resistance, and high creep resistance.
