Abstract
Precipitates formed before and at the peak stage of secondary hardening in tempered low alloy steels were examined by atom probe - field ion microscopy. The present AP analysis confirmed the existence of Mo2C, NbC, and V4C3 even before and at the peak stage of secondary hardening. In addition to alloy carbides, existence of Mo clusters and Nb clusters were found. Formation of such clusters may play an important role in secondary hardening of Mo and Nb steelsKeywords
