1. Microstructure and Inclusion Characteristics in Steels with Ti-oxide and TiN Additions
Abstract : Non-metallic inclusions in steels are generally considered to be detrimental for mechanical properties. However, it has been recognized that certain inclusions, such as Ti-oxide and TiN, can serve as potent nucleation sites for the formation of intragranular ferrite (IGF) in low-alloy steels. READ MORE

2. Phase separation in duplex stainless steel: characterization and mitigation
Abstract : Duplex stainless steel (DSS) is a category of widely used stainlesssteel, which are strategically important in a variety of applications such asin the food industry, chemical engineering plants and nuclear power plants,due to their attractive combination of mechanical properties and corrosionresistance. However, these steel grades are sensitive to the so-called ‘475°Cembrittlement’, because of a phase separation (PS) phenomenon in theferrite phase, which decomposes into Fe-rich ferrite (α) and Cr-rich ferrite(α'), when exposed to temperatures within the miscibility gap.
