Aluminum alloy is heated to around 300 ℃ normally, heat preservation after a period of time, along with the process known as annealing furnace cooling to room temperature. When annealing, the solid solution will decompose and the second phase particle will gather, which can remove the internal stress of the casting, keep the size of the casting stable, avoid deformation and enhance the plasticity of the casting.
Heat the castings to nearly in eutectic melting point, and then at that temperature for longer, and then rapidly cooling, let the yuan to strengthen group best dissolved, save the state of high temperature until the room temperature, the process is called solid solution treatment. Solid solution treatment can enhance the strength and plasticity of the casting and improve the corrosion resistance of the alloy. The effect of solid solution treatment is usually related to the temperature of solid solution treatment, the heat preservation time of solid solution treatment and the cooling speed.
