Problems solved by technology
However, although the structure of high-entropy alloys is generally a simple solid solution structure, the extremely high solid solubility makes most high-entropy alloys prone to macro-segregation and micro-segregation during casting, making it difficult to achieve industrial mass production and application.

Abstract
The invention relates to the technical field of metal materials, and provides a preparation method of a eutectic high-entropy alloy wire and a eutectic high-entropy alloy wire, comprising a smelting step for smelting and pouring raw materials into a mold; In the bar material obtained by casting, the uneven surface layer is removed; the rolling step is used for hot rolling the bar material processed by the turning step; the first drawing step is used for the bar material processed in the rolling step. Perform online heating and drawing to form the first wire; the second drawing step is used to draw the first wire processed by the first drawing step at room temperature; the annealing step is used to draw the second wire after the second drawing step. The wire processed in the drawing step is heated and cooled to room temperature in air; the AlCoCrFeNi2.1 eutectic high-entropy alloy wire prepared by the invention has a uniform diameter, a continuous surface without defects, a uniform internal structure, and has strong plasticity and thermal stability.
Description
technical field [0001] The invention relates to the technical field of metal materials, in particular to a preparation method of a eutectic high-entropy alloy wire and a eutectic high-entropy alloy wire. Background technique [0002] Traditional metal wires, such as pearlite steel wires, have been widely used in daily life and industrial production. Although pearlitic steel wire can achieve high strength, its plasticity is poor and decreases significantly with increasing strength, and its thermal stability is low. In some complex service environments, pearlitic steel wires still face many insurmountable challenges. [0003] In recent years, High Entropy Alloys (HEAs) have attracted widespread attention. Alloy system between 5%-35%. Compared with traditional alloys, high-entropy alloys show more excellent mechanical properties, such as strong plastic bonding, high fracture toughness, impact resistance, etc., and become a new type of metal material with great application po...
