Role of 19 Boundaries in Abnormal Grain Growth of Goss Grains in Fe-3Si Steel Approached by Solid-state Wetting.

摘要

The pancake-shaped growth of Goss grains in Fe-3%Si steel is approached by solid-state wetting mechanism. The fraction of grains with ∑9 relation with Goss grains in the 0.3 mm thick specimens after primary recrystallization is higher near the surface than at the center. This result indicates that the probability of solid-state wetting is higher near the surface than at the center, leading to the pancake-shaped growth.
