Characterization of 475°C Embrittlement of Duplex Stainless Steel Microstructure via Scanning Kelvin Probe Force Microscopy and Magnetic Force Microscopy

“…[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] This has been attributed to phase separation mechanisms, primarily in the ferrite phase, due to the existing miscibility gap in the Fe-Cr equilibrium phase diagram. 7,29,30 Dependent on the chemical composition of the alloy, the ferrite either decomposes based on nucleation and growth or spinodal decomposition 5,22,23,[31][32][33][34] to Cr-enriched α and Fe-enriched α , or by nucleation of further precipitates such as G-phase, 5,[35][36][37][38][39][40] R-phase, 5,39,[41][42][43][44] secondary austenite (γ 2 ), 5,7 Laves phases, 41,44,45 chromium carbides, 5,7 and nitrides. 5,7,12,…”
