cracks in superalloys are braze repaired after notching or cutting away material adjacent the cracks , filling the recess with a braze component containing a melting point depressant and subjecting the repair area to a first elevated temperature to form a melt . the melting point of the repair region is raised by diffusing the depressant into the braze material and repair region at second and third elevated temperatures lower than the first elevated temperature to form a repaired superalloy exhibiting highly desirable properties .
