“…Therefore, the development of advance power plant, such as supercritical (SC) and ultra-supercritical (USC) power plants has been a main subject in many countries (Viswanathan et al, 2005). This development is targeted to achieve higher efficiency of the power plant, so that the CO 2 emission can be reduced.…”

The development of supercritical (SC) and ultra-supercritical (USC) power plants requires materials with better corrosion properties. Deep understanding on the oxidation mechanism in the boiler environment is one of the important factors to support this development. In this work, high temperature oxidation of Fe-Cr steels in steam condition is reviewed. Several mechanisms that explain the effect of water vapor in the oxidation behavior the steel were presented.

“…These have been used to date in relatively short term applications such as turbine engines in the aerospace industry. Forecasted requirements for USC applications have set the targets at minimum creep strength of 100 MPa at 100000 h of service [1][2][3][4][5][6][7]. Since the microstructure of most of the candidate nickel base alloys has not been investigated after such long exposure periods of time, modelling activity has proven to be helpful in predicting the material microstructural response under simulated service conditions [8].…”

Current energy drivers are pushing research in power generation materials towards improved efficiency and improved environmental impact. In the context of new generation ultra-supercritical (USC) power plant , this is represented by increased efficiency, service temperature reaching 750 o C, pressures in the range of 35 -37.5 MPa and associated carbon capture technology. Ni base alloys are primary candidate materials for long term high temperature applications such as boilers. The transition from their current applications, which have required lower exposure times and milder corrosive environments, requires the investigation of their microstructural evolution as a function of thermo-mechanical treatment and simulated service conditions, coupled with modelling activities that are able to forecast such microstructural changes. The lack of widespread microstructural data in this context for most nickel base alloys makes this type of investigation necessary and novel. Alloy INCONEL 617 is one of the Ni-base candidate materials. The microstructures of four specimens of this material crept at temperatures in the 650 o C-750 o C range for up to 20000 h have been characterised and quantified. Grain structure, precipitate type and location, precipitate volume fraction, size and inter-particle spacing have been determined. The data obtained are used both as input for and validation of a microstructurally-based CDM model for forecasting creep properties.

“…The need for more expensive Ni alloys as materials of construction is due to the need for creep resistance [4][5][6][7] Figure 2 [7] compares the creep rupture life for Ni alloys to ferritic and austenitic steels for boiler tube applications. The temperature limit for advanced ferritic alloys is 898 K (625°C) and for austenitics is 948 K (675°C).…”

This special section of Metallurgical and Materials Transactions is devoted to materials challenges associated with coal based energy conversion systems. The purpose of this introductory article is to provide a brief outline to the challenges associated with advanced combustion and advanced gasification, which has the potential of providing clean, affordable electricity by improving process efficiency and implementing carbon capture and sequestration. Affordable materials that can meet the demanding performance requirements will be a key enabling technology for these systems.
