摘要：Strontium-modified aluminium alloys may be produced by using strontiumperoxide as the source of strontium. The strontium peroxide may be mixed with moltenaluminium or molten aluminium alloy in a quantity sufficient to give the desired strontiummetal content in the alloy being produced. The temperature of the molten aluminium oraluminium alloy with which the strontium peroxide is mixed is preferably at least 1000DEG C. The strontium peroxide alloys produced may be master alloys for use in theproduction of casting alloys, or may be casting alloys. Strontium acts as a grain refiner insuch alloys.
