The initiation curve of carbide precipitation at grain boundaries was determined by electronmicroscope observation of the specimens aged for various times at 350∼980°C. Carbides are easily recognized in 10 min above 700°C, but not recognized even after 9×103 h at 350°C. Under the condition near the initiation curve a specimen can have boundaries with or without precipitates. This fact shows that the precipitation depends on a crystallographic characteristic of grain boundaries. The rate of intergranular corrosion under the potentiostatically controlled condition in 1N-H2SO4 solution decreases with aging time and becomes constant after minimum, while the rate attacked under the naturally immersed condition in boiling 10N-HNO3 solution increases with aging time and becomes constant after passing through a maximum. In both water-quenched and aged specimens, the depth of intergranular corrosion decreases at coincidence boundaries and twin boundaries with [100], [110] and [111] rotation axes.
