1. Microstructural Characterization of Expanded Austenite in 304L and 904L Austenitic Stainless Steels
Abstract : Austenitic stainless steels are among the most used materials in modern industry, mainly because of their superior corrosion resistance. However, low hardness and poor tribological properties often restrict their applicability. READ MORE

2. Low-temperature carburizing/nitriding of austenitic stainless steels - Influence of alloy composition on microstructure and properties
Abstract : Austenitic stainless steels are among the most used materials in applications where corrosion resistance is important, as the food, pharmaceutical, chemical, oil and gas industries. However, low hardness and poor tribological properties is often an obstacle for their applicability. READ MORE

4. Carbothermal synthesis of nano-structured metal, carbides and nitrides, using solution processed precursors; from precursor to product
Abstract : This thesis describes how solution chemical based carbothermal syntheses can be used for the synthesis of nanostructured zirconium carbide and nitride nanophase powders as well as a nickel-metal coating on NbC for use as a sintering agent. The focus is on the development of novel synthesis routes using atomic or small nanoscale level mixing of the metal oxide and carbon source in the starting precursors, enabling the use of lower synthesis temperatures and non-agglomerated nanosized powders.

5. Theoretical and Experimental Studies on Early Transition Metal Nitrides for Thermoelectrics
Abstract : Thermoelectricity transforms temperature gradients across thermoelectric material into an external voltage through a phenomenon known as the Seebeck effect. This property has resulted in niche applications such as solid-state cooling for electronic and optoelectronic devices which exclude the need for a coolant or any moving parts and long-lasting, maintenance-free radioisotope thermoelectric generators used for deep-space exploration.
