Copper-alloyed Ti-8Si alloy and preparation method thereof

A copper-alloyed Ti-8Si alloy and a preparation method thereof. The copper-alloyed Ti-8Si alloy is prepared from titanium powder, silicon powder and copper powder. The preparation method includes the steps of: uniformly mixing the titanium powder, silicon powder and copper powder and performing high-energy ball milling to partially alloy the powder material; drying and sieving the ball-milled powder material and compression-molding the dried powder material to form a briquette; and finally performing vacuum pressure-free sintering to completely alloy the briquette. The Ti-(8-0.08x)Si-xCu alloy has uniform surface component, is increased in compactness, microhardness, elasticity modulus, fracture toughness, anti-oxidizing property, corrosion resistance and frictional wear performance at certain degrees, and has a wide application prospect in the fields of aerospace, traffic transportation and weapon equipment. 种Cu合金化的Ti-8Si合金及其制备方法，其特征在于：它的制备原料为Ti粉、Si粉和Cu粉；制备方法为首先，将Ti粉、Si粉和Cu粉混合均匀后进行高能球磨，使其部分合金化，再将球磨所得的粉料干燥，过筛
