MULTI-STEP HEAT TREATMENT FOR SUPERALLOYS ABSTRACT OF THE DISCLOSURE This invention relates to a multi-step heat treatment method for increasing the elevated temperature mechanical properties of nickel base superalloys. The heat treatment method is particularly applicable to those conventional alloys which have a cast structure consisting essentially of a gamma matrix containing a gamma prime second phase precipitate and regions of low melting constituents. The effect of the process of the invention is to maximize the volume fraction of the fine gamma prime precipitate, by a solution treatment and reprecipitation, without causing significant incipient melting. -1-
