英文摘要The thermal aging effects on mechanical properties and microstructures in China low-activation martensitic steel have been tested by aging at 550 degrees C for 2,000 hours, 4,000 hours, and 10,000 hours. The microstructure was analyzed by scanning and transmission electron microscopy. The results showed that the grain size and martensitic lath increased by about 4 mu m and 0.3 mu m, respectively, after thermal exposure at 550 degrees C for 10,000 hours. MX type particles such as TaC precipitated on the matrix and Laves-phase was found on the martensitic lath boundary and grainboundary on aged specimens. The mechanical properties were investigated with tensile and Charpy impact tests. Tensile properties were not seriously affected by aging. Neither yield strength nor ultimate tensile strength changed significantly. However, the ductile-brittle transition temperature of China low-activation martensitic steel increased by 46 degrees C after aging for 10,000 hours due to precipitation and grain coarsening.
