3. Titania Nanoscale Films and Surfaces : Surface Science Investigation of Structure and Properties
Abstract : This thesis presents surface science studies, investigating several aspects of titanium dioxide at the atomic scale. The greater part of this work is devoted to the preparation by chemical vapor deposition (CVD) of titanium(IV) tetraisopropoxide (TTIP) of ultrathin TiO2 or TiOx films on Au(111). READ MORE

4. Wettability and Agglomeration Characteristics of Non-Metallic Inclusions
Abstract : In this thesis, both the wettability and the agglomeration characteristics of non-metallic inclusions in liquid iron/steel were studied by using both experimental results and thermodynamic considerations. The mechanisms of the wettability of different types of inclusions were discussed. READ MORE

5. 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
