To investigate the evolution of microstructure damage degree and the precipitated phases of heat-resistant metal in power plant under high temperature and stress environment, the high-temperature aging tests were conducted to investigate the aging behavior of T91 steel at different temperatures and stress. The optical microscopy, scanning electron microscopy, and transmission electron microscopy were used to investigate the structure and precipitated phases, the results showed that the orientation characteristics of tempered martensite was dispersed, and the grain size is obviously increased. The density of dislocation decreased with increasing temperature and stress. The important strengthening phase of M23C6 (M=Fe, Cr) was coarsened by the diffusion of main alloying elements Cr, while the smaller size MX (M=Nb,V; X=C, N) phase distributed in the grain is relatively stable in the aging.

ABSTRACT This study was aimed to explore the high-temperature oxidation behaviour of AlTiSiN and AlCrSiN coatings. The coatings were deposited using arc ion plating and annealed in air at a temperature range of 600–1000°C for 2 h. The results showed that the oxidation of AlTiSiN coatings started at 900°C and failed at 1000°C. However, the oxidation of AlCrSiN was different from AlTiSiN coatings, which commenced at 800°C and kept stable till 1000°C. The hardness of the as-deposited AlTiSiN coatings dropped from 25.2 to 16.5 GPa after 1000°C annealing, while AlCrSiN coatings decreased from 24.2 to 20.5 GPa. The AlCrSiN coating exhibits a better high-temperature oxidation resistance than AlTiSiN coating.
