1. Furnace Wall Corrosion in a Wood-fired Boiler
Abstract : The use of renewable wood-based fuel has been increasing in the last few decades because it is said to be carbon neutral. However, wood-based fuel, and especially used wood (also known as recycled wood or waste wood), is more corrosive than virgin wood (forest fuel), because of higher amounts of chlorine and heavy metals.

2. Oxidation, Creep and Fatigue Synergies in Cast Materials for Exhaust Manifolds
Abstract : The future development of engines of heavy-duty vehicles towards reduced CO2 emission will increase the exhaust gas temperature and render the exhaust atmosphere more corrosive. The current service material of exhaust gas components - a ferritic ductile cast iron called SiMo51 - will soon meet its upper-temperature limit. READ MORE

3. Is water a crucial factor in the oxidation of FeCrAl alloys?
Abstract : FeCrAl alloys are much used at high temperatures because the formation of a dense and slow-growing alumina scale provides resistance towards oxidation and high temperature corrosion. While the FeCrAl alloys are primarily intended for temperatures above 950ºC, they are sometimes used at lower temperature, for example as supports in automotive catalysts. READ MORE

4. High Temperature Fatigue Behaviour of Austenitic Stainless Steel : Microstructural Evolution during Dwell-Fatigue and Thermomechanical Fatigue
Abstract : The global energy consumption is increasing and together with global warming from greenhouse gas emission, a need for more environmentally friendly energy production processes is created. Higher efficiency of biomass power plants can be achieved by increasing temperature and pressure in the boiler section, this would increase the generation of electricity along with the reduction in emission of greenhouse gases e.

5. Stacking faults, deformation-induced martensite and micromechanics of metastable austenite in steels studied by high-energy synchrotron X-ray diffraction
Abstract : Austenitic stainless steels are known for their remarkable corrosion resistance and exhibit a very high ductility and toughness. They posses the face centered cubic crystal structure. READ MORE
