1. Additive Manufacturing of Ferritic Materials : A Journey from Stainless Steels to High-Entropy Alloys
Abstract : Design of new materials with complex geometries is an important part of new innovative solutions for technical applications. With the use of additive manufacturing (AM), the design possibilities are endless and geometries that are impossible to manufacture by conventional techniques are available. READ MORE

2. Inclusions and/or Particles Engineering for Grain Refining Purposes in Ferritic Fe-20mass%Cr alloys
Abstract : Compared to more common used austenitic stainless steels, ferritic stainless steels contain very low amounts of the expensive alloying element Ni. In addition, they have good corrosion properties, but are sometimes suffering from poor weldability and bad mechanical properties. READ MORE

3. Chlorine Induced Corrosion in Biomass and Waste Fired Boilers: Laboratory and Field Investigations
Abstract : The fireside corrosion in biomass and waste fired boilers is widely believed to arise from the presence of chlorine-containing compounds in the fuels. Although many researchers have studied the influence of such compounds on the high temperature corrosion of various steels, the mechanisms underlying chlorine-induced corrosion are still poorly understood.

4. Modelling phase separation in Fe-Cr alloys : A continuum approach
Abstract : The formation of Cr-rich and Fe-rich domains upon ageing of an initially homogeneous Fe-Cr alloy at elevated temperatures (300-600 ºC) is commonly referred to as phase separation. The behaviour originates from a miscibility gap in the Fe-Cr phase diagram. READ MORE

5. 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
