Abstract

Abstract: Aging precipitation behavior of the two solid-solution strengthened Ni-based alloys(617 and 625) has been investigated. The results revealed that the M₂₃C₆ and M₆C carbide particles precipitated both at the grain boundaries and inside grains, and the γ phase particles were situated at intragranular sites in the process of aging at 760 ℃ for two alloys. In addition, γ″ phase precipitated at grain boundaries and stacking faults in the aged alloy 625. The carbide particles discontinuously dispersed at grain boundaries after aging for up to 3 000 h for alloy 617; however, the 5 000 h aging induced the coalescence of the carbide particles. After aging up to 5 000 h, the size of precipitates inside grains remained basically stable for alloy 617. The carbides precipitates dispersed continuously at inter-granular site were observed in the alloy 625 aged for 3 000 h and an increase of aging time resulted in the growth of carbide particles. The size of intragranular particles kept almost unchanged after aging for up to 3 000 h for alloy 625; however, the presence of a number of M₆C particles was visible for alloy 625 after 5 000 h. The impact absorbed energy obviously declined for two alloys after aging. Aging embrittlement of the alloy 625 is greater than that of the alloy 617.
