ժҪ T122 steel has been used to produce superheater or reheater of ultra supercritical boilers. With the help of chemical phase extraction and microstructure characterization, the authors of the paper investigated the performance of aging precipitates of T122 steel, such as M23C6 carbide, Laves phase, MX phase and cu-rich phase, discussed the strengthening mechanism of the steel, and calculated athermal yield stress of lath substructure, dislocations and precipitates of the steel.
