Abstract:

High performance parts of Al 356 plus Be and Mg alloy ZH62A for aircraft and missile applications can be centrifugally cast in permanent molds and heat treated to tensile strengths averaging 53,000 psi and 40,000 psi respectively where the casting design is menable to the process. The effects of pouring temperature, mold temperature, mold material, mold coating, and centrifugal force on the quality of the castings were determined. The optimum condition for each of these variables contributes towards developing within t e solidifying casting a high thermal gradient necessary for maxi um properties.
