The invention relates to high-entropy
alloy powder containing amorphous nanocrystalline and a fabrication method thereof. A high-entropy
alloy coating is composed of, by atomic percent, 14.3% of Al, 14.3% of Fe, 14.3% of Co, 14.3% of Ni, 14.3% of Cr, 14.3% of Mo and 14.2% of Si, and the total percentage is 100%. The fabrication method includes the following steps: S1, high-entropy
alloy master alloy is fabricated through a medium-frequency induction
smelting technique, wherein weighed metallic raw materials are put in a carborundum
crucible in sequence and according to melting points from low to high, then the carborundum
crucible is vacuumized until the pressure is lower than 6.0*10MPa;
argon gas is inflated in the carborundum
crucible, the metallic raw materials are melted under the condition that the pressure of the
argon air is 3*10-2 Pa, the
smelting current is 75A, the melting time is 25min, the
alloy composition is segregated with the assistance of
electromagnetic stirring, the
alloy composition is poured into a magnesia framework after the
alloy composition is melted completely, and the high-entropy alloy master alloy which is even in ingredients is obtained; S2, high-entropy alloy powdered materials are fabricated through gas atomization equipment. The fabrication method of the high-entropy alloy
powder is used for fabricating the high-entropy
alloy coating containing the amorphous nanocrystalline or bulk alloy materials of more superior performance.
