1. High Temperature Corrosion of Cast Irons and Steels
Abstract : During the last decades, tougher competition and stiffer government policies have forced the automotive industry into a race for safer, cleaner and more fuel-efficient vehicles at low cost. As a consequence, exhaust systems should resist to increased working temperatures. READ MORE

2. High temperature corrosion in biomass-fired energy applications : Alloying effects and test environment comparisons
Abstract : To reduce the greenhouse effect, the use of renewable fuel has to be increased. As renewable fuel has different characteristics compared to fossil fuel regarding content of trace metals, alkali, chlorine and sulphur, the corrosion characteristics in high temperature energy processes have to be evaluated.

3. Net-Shape Consolidation of Water-Atomised and Gas-Atomised Steel Powder Towards Full Density
Abstract : Powder metallurgy (PM) provides resource- and cost-efficient routes to create near-net shape products compared to conventional metal fabrication techniques. To improve the mechanical performance of PM steels, it is a prerequisite to enhance the density of the material. READ MORE

4. High-Temperature Durability Prediction of Ferritic-Martensitic Steel
Abstract : Materials used for high-temperature steam turbine sections are generally subjected to harsh environments with temperatures up to 625 °C. The superior creep resistance of 9–12 % Cr ferritic-martensitic steels makes them desirable for those critical steam turbine components. READ MORE

5. Deposit Induced Corrosion in Biofuel Combustion
Abstract : Deposit induced corrosion is one of the main mechanisms for attack on heat exchangers in biofuel boilers. This severe corrosion decreases the obtainable steam temperature in boilers, thereby the efficiency in production of electricity is reduced. Deposit formation from the gas on superheater tubes are is generally referred to as fouling. READ MORE
