Fig. 6: Simulated time evolution of the Mn concentration in the GB plane.
From: Segregation-assisted spinodal and transient spinodal phase separation at grain boundaries
a 2.9, b 3.3, and c 9 at.% Mn alloy compositions were studied. For an 2.9 at.% Mn alloy (below the jump composition), segregation increases monotonically and it is stable even after long simulation times. For a composition very close to the jump composition (3.3 at.% Mn), a spinodal GB phase separation is observed. Above the jump composition (9 at.% Mn) a transient spinodal regime is observed before reaching the equilibrium Mn segregation level.
