Abstract

The invention discloses a lightweight wear-resistant aluminum alloy softball bat material, which is prepared from zinc, silicon, titanium, beryllium, a nano-palladium-niobium-silicon carbide powder mixture, and the balance of aluminum. The invention also provides a preparation method of the lightweight wear-resistant aluminum alloy softball bat material. The preparation method comprises the following steps: adding aluminum, zinc, silicon, titanium, beryllium and a refining agent into a melting furnace, melting at high temperature and removing slag, so as to obtain a mixing solution; adding thenano-palladium-niobium-silicon carbide powder mixture into the mixing solution, carrying out ultrasonic treatment and heat preservation, casting for molding, and cooling to room temperature, so as toobtain the lightweight wear-resistant aluminum alloy softball bat material. The aluminum alloy material has light weight and good wear resistance, and is suitable for use in a softball bat.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to a lightweight wear-resistant aluminum alloy softball bat material and a preparation method thereof. Background technique [0002] Softball is developed from baseball. Compared with baseball, softball requires a small field, a large ball, and slow ball speed, which are widely loved by people. A softball bat is a stick used to hit the ball in a softball game. It is commonly made of metal, bamboo, plastic, carbon lead, magnesium, fiberglass, ceramics or other synthetic materials. At present, metal bats are mainly used. Aluminum bats are widely used because of their advantages of light weight, no running-in, and better durability. However, they have poor wear resistance and low hardness. Long-term used bats are easy to break and have many surface pits. , cannot meet people's needs. Contents of the invention [0003] Based on the technical problems existing in the backgrou...
