Abstract
SUMMARYA combined TEM and optical metallographic technique has been applied to microstructures in the heat affected zone in two high‐strength, low‐alloy steels with carbon equivalent 0·37 and microalloyed with Nb (0·024%), Ti (0·015%) and Nb (0·025%), V (0·05%) respectively. Volume fraction, size distribution and composition of the carbonitrides of microalloying elements were determined as function of distance from the fusion line and compared with other microstructural features, such as primary austenite grain size. Differences in microstructure are attributed to the higher stability of the Ti, Nb particles during the weld thermal cycle.
