Abstract

The invention discloses a high-entropy material for preparing sports equipment. The general formula of the material is FeaNibAlcTidXeYf, wherein a is larger than or equal to 30 and smaller than or equal to 35, b is larger than or equal to 28 and smaller than or equal to 30, c is larger than or equal to 10 and smaller than or equal to 20, d is larger than or equal to 5 and smaller than or equal to 15, e is larger than or equal to 0 and smaller than or equal to 20, f is larger than or equal to 0.5 and smaller than or equal to 1, X is one or a combined element of more than two of Co, Ta, Nb, Cr or W, and Y is one or a combined element of more than two of La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er or Tm. By optimizing alloy components, the high-entropy material has greater advantages compared with a traditional alloy, has the performance characteristics of high strength, high hardness, tempering softening resistance, wear resistance and the like, and is suitable for preparing the sports equipment such as supporting structure components and rackets.

Description

technical field [0001] The invention relates to the technical field of high-entropy amorphous alloys, in particular to a high-entropy material used for preparing sports equipment and a preparation method thereof. Background technique [0002] Sports equipment is the general term for various apparatuses, equipment and articles for use in competitive sports competitions and body-building exercises. Because of the high strength and modulus of metal materials, sports equipment generally uses metal materials as a support or stable structure, but often the hardness and wear resistance of metal materials are insufficient, resulting in damage to sports equipment. [0003] Even if it is the same appliance, the materials used in different structures are generally different, such as rackets (such as badminton rackets, tennis rackets, etc.), the racket shaft, frame and strings are generally made of different materials, and have different functional demands: The shaft needs to be light,...
