Abstract
Abstract In this study the effect of temperature and carbide distribution on the abnormal grain growth of 0.023% C lamination steel was evaluated. It was found that the abnormal grain growth mechanism was not affected by temperature even though the 788°C decarburization treatment was done in the ferrite plus austenite region while at 704°C decarburization took place in the ferrite plus cementite region. This would indicate that the controlling factor in the abnormal growth mechanism is the dislocation/carbide interaction produced during initial straining which subsequently results in polygonization on heating.
