| titleOfInvention | Aluminum-yttrium-phosphorus interalloy and preparation method thereof |
| abstract | The invention belongs to the field of metal materials, and relates to an aluminum-yttrium-phosphorus interalloy for refining primary crystal silicon in a eutectic and hypereutectic aluminum-silicon alloy and a preparation method thereof. In the interalloy system, P exists in the form of yttrium phosphide. The alloy comprises the following chemical components in percentage by mass: 80.0-97.5% of aluminum, 1.5-16.0% of yttrium and 0.5-5.0% of phosphorus. The preparation method comprises the following steps: proportionally preparing commercially pure aluminum, aluminum-phosphorus interalloy and commercially pure yttrium or aluminum-yttrium alloy; melting the commercially pure aluminum to 800-1100 DEG C in a smelting furnace, adding the aluminum-phosphorus interalloy, stirring for 5-10 minutes, adding the commercially pure yttrium or aluminum-yttrium alloy, and heating to 1200-1400 DEG C; and after completely reacting and uniformly stirring, directly casting into an ingot or preparing a wire. The aluminum-yttrium-phosphorus interalloy has favorable dual deterioration effects on the silicon phase in the eutectic and hypereutectic aluminum-silicon alloys, and can obviously enhance the mechanical properties of the alloy. |
