摘要： A method is provided for producing a quantity of high grade metal alloy containing reactive elements, such as aluminum and titanium in a nickel, cobalt or iron base. According to the method of the invention a master heat of ingot containing reactive elements, such as aluminum and titanium in a nickel, cobalt or iron base is formed by some vacuum melting process, such as by vacuum- induction melting. A second, larger master heat of ingot of air-melting grade material is formed, as by argon oxygen decarburization with no reactive elements present. The two ingots are mechanically joined together to form one ingot which is subsequently remelted in the investment casting process. The resulting blend produces a standard alloy which means the metallurgical specifications for metal used in the investment casting of gas turbine components for use in aircraft, and components for turbochargers for use in internal combustion powerplants.
