Creep-resistant die cast zinc alloys
摘要:
A creep-resistant die casting is formed of a zinc-base alloy comprising about 4 to 12 percent copper and about 2 to 4 percent aluminum. The die casting is characterized by an intimate dispersion of fine epsilon and eta phases effective to retard slip and thereby enhance creep resistance.
