Influence of neighbourhood on abnormal Goss grain growth in Fe–3% Si steels: Formation of island grains in the large growing grain

A new approach based on the concept of curvature-driven migration of grain boundaries in the presence of particle distribution has been used to study the abnormal grain growth of Goss grains in silicon steels. The morphological aspect of the abnormal growth is considered by the introduction of the l...

Zusammenfassung:A new approach based on the concept of curvature-driven migration of grain boundaries in the presence of particle distribution has been used to study the abnormal grain growth of Goss grains in silicon steels. The morphological aspect of the abnormal growth is considered by the introduction of the limit radius of neighbourhood. This critical radius is able to explain the presence of island grains observed inside the growing Goss grain. These island grains are formed as a result of large neighbouring grain resistance.
