The microstructure changes and creep behavior of coarse-grained and HPS-processed steel were investigated at 500-700 degrees C under the application of different loads. It was found that the processing of S304H steel led to a significant improvement in creep strength at 500 degrees C. However, a further increase in creep temperature to 600 degrees C and 700 degrees C led to the deterioration of creep behavior of HPS-processed steel. The microstructure results suggest that the creep behavior of HPS-processed steel is associated with the thermal stability of the SPD-processed microstructure. The recrystallization, grain growth, the coarsening of precipitates led to a reduction in creep strength of the HPS-processed state. It was also observed that in the HPS-processed microstructure the fast formation of sigma-phase occurs. The sigma-phase was already formed during slight grain coarsening at 600 degrees C and its formation was enhanced after recrystallization at 700 degrees C.
