Evolution of microstructure and changes in hydrogen embrittlement resistance of CLAM steel after long-term aging
Source abstract
Abstract
To investigate the changes in hydrogen embrittlement (HE) resistance of China Low Activation Martensitic (CLAM) steel during thermal aging, CLAM steels were aged at 550 °C and 600 °C up to 5000 h. The evolution of microstructure, including the evolution of subgrains, the growth of M 23C 6 carbides and MX carbonitrides, as well as the formation of Laves phase, were carefully characterized. The observed trend revealed an initial increase followed by a subsequent decrease in HE resistance upon prolonged aging durations. The mechanisms for changes in HE resistance were analyzed based on the orientation relationship between precipitates and matrix.
