Phase Analysis of the Precipitates in an Alloy 600/182 Weld

Abstract:

The precipitates in the base metal and the fusion zone of an Alloy 600/182 weld were characterized through a transmission electron microscopy. Precipitates in the Alloy 600 base metal were identified as Cr7C3. On the other hand, (Nb,Ti)C, Al-rich and Ti-rich oxides were found on the dendritic interfaces, and tiny Cr-rich M23C6 were distributed on the grain boundaries in the Alloy 182 fusion zone.
