Improved “Superalloy” Properties Through Forging 650091

The generally beneficial effects of forging on precipitation hardened heat resistant alloys can be considerably increased by the addition of titanium and aluminum to the material. These elements, however, cause complications in the casting and forging processes, but by applying controlled forging programing, these disadvantages can be overcome. This paper describes the desirable and undesirable characteristics of a Ti + A1 alloy and explains some of the principles involved in setting up programed forging cycles to produce improved material properties such as optimum strength, uniformity, and reproducibility.
