Popis: Crystallization and redissolution of giant intermetallic compounds in Al-4.5%Mg alloys containing 0.25%Cr were studied. Giant intermetallic compounds in those alloys crystallized at temperatures from 640°C to 680°C. The higher the crystallization temperature is, the larger the size is and the less the number is. The compounds redissolve so slightly in molten alloys and it takes an hour to dissolve even at 800°C. A giant intermetallic compound CrAl7 has micro-vikers hardness Hv 429 and density 3.12g/cm3.
