Abstract
The influence of the deoxidation product size distribution in determining the prior austenite grain and the subsequent balance between inter- and intragranular nucleation has been studied in C-Mn-Nb weld metals. The growth of austenite appears to be controlled by pinning of the grain boundaries by the deoxidation inclusions, and follows the classical Zener precipitate-boundary interaction equations. Some evidence of the direct nucleation by inclusions of the acicular ferrite phase has been obtained.
