Embodiment 1
[0018] A zinc-lithium alloy with 450-degree smelting, Li-containing, flame-retardant, high wear-resistant and high thermal conductivity. By weight percentage, the chemical composition is: Li:1.4wt.%, Si:8.6wt.%, Ba:0.3wt.%, Ge:0.6wt.%, Mo:0.4wt.%, Y:0.8wt.%. , V:0.3wt.%, Nd:0.1wt.%, Yb:0.2wt.%, the balance is zinc. The preparation method of the alloy: add the above-mentioned raw materials into the induction furnace under the atmospheric environment, and use a silicon carbide crucible. Induction heating to 450 degrees to form an alloy solution, and use the electromagnetic effect to fully stir for about 10 minutes. The alloy liquid is kept at 450 degrees for 10 minutes and poured into the equipment at the same level as the hot top for semi-continuous casting, and the ingot moving speed is 10m / min. The ingot is deformed at room temperature, and the amount of rolling in each pass is 12%; every 3 passes of rolling requires an intermediate heat treatment to eliminate work hardenin...
