Abstract
Heat treatments are described which improve subsequent HIP treatment results of superalloy articles. The heat treatments substantially eliminate certain low melting phases which otherwise would cause problems relating to gas entrapment during a HIP process. The articles are heated to a temperature near but below the intended HIP temperature for a period of time sufficient to reduce the low melting phase.
