Creep behaviour and microstructure evolution in AISI 316LN +0.1 wt.% Nb steel at 600 and 625°C
Original language description
The paper deals with microstructural evolution in the AISI 316LN + 0.1 wt.% Nb steel during long-term creep exposure at 600 and 625°C. The following minor phases formed: Z-phase (NbCrN), M23C6, M6X (Cr3Ni2SiX type), h-Laves (Fe2Mo type) and s-phase. M6X gradually replaced M23C6 carbides. Primary Z-phase particles were present in the matrix after solution annealing, while secondary Z-phase particles formed during creep. Precipitation of Z-phase was more intensive at 625°C. The dimensional stability of Z-phase particles was excellent and these particles had a positive effect on the minimum creep rate. However, niobium also accelerated the formation and coarsening of s-phase, h-Laves and M6X. Coarse particles, especially of s-phase, facilitated the development of creep damage, which resulted in poor long-term creep ductility.
