G115 martensitic steel is anticipated to be one of the preferred candidate materials in ultra-super critical (USC) power plants with steam temperatures above 650°C. Microstructure evolutions and mechanical properties of G115 martensitic steel after applying various heat treatment processes were investigated. The results demonstrate that the main precipitate in G115 martensitic steel after applying various heat treatment processes is M23C6 phase with Cr enrichment. The time required for M23C6 ph...

Novel G115 martensitic steel (G115 steel) with excellent creep properties, oxidation resistance and low manufacturing cost, has been widely used for ultra-super critical (USC) power plants. Microstructural evolutions were characterized using multiple methods, and their effects on mechanical properties of G115 steel after secondary normalizing process at different temperature (1000 °C, 1050 °C and 1100 °C) were also investigated. The results show that the average width of martensitic lath decr...
