Abstract
A method for post-weld heat treatment of a without a filler material welded high strength component made of a gamma prime (γ') strengthened superalloy can include providing the welded component, heating the welded component by applying a rapid heating-up rate in the range of 20° C./min to 40° C./min during the entire temperature range from room temperature (RT) up to a temperature Tof at least 1000° C., holding the welded component at Tand then heating the component by applying a slow heating-up rate of about 5° C./min to a final temperature T, then holding the welded component at Tfor a time tsufficient for at least partially dissolving the gamma prime phase in a weld of the welded component and also in a base material surrounding the weld, and cooling the component with a cooling rate that is greater than or equal to about 20° C./min.
