6. Synthesis of Transition Metal Aluminides from Elemental Powder Mixtures
Sammanfattning : Structural components such as those used in gas turbines for energy conversion applications, are subjected to high loads at elevated temperatures. In order to ensure that the components survive under these conditions for a sufficiently long time, it is imperative to select materials with good high temperature properties like strength and corrosion resistance.

7. Low-temperature carburizing/nitriding of austenitic stainless steels - Influence of alloy composition on microstructure and properties
Sammanfattning : 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. LÄS MER
8. ROLE OF SURFACE OXIDES IN SINTERING OF CHROMIUM-ALLOYED STEEL POWDER
Sammanfattning : During water-atomisation and handling of steel powder the surface inevitably oxidises. The surface bound oxide is an important factor in the processing of powder metallurgical (PM) steels, especially in case the powder contains elements forming stable oxides, such as Cr, Mn, and Si.

9. Microstructural Characterization of Expanded Austenite in 304L and 904L Austenitic Stainless Steels
Sammanfattning : 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. LÄS MER
10. On a novel technique for preparation and analysis of the implant surface and its interface to bone
Sammanfattning : The ultrastructural and biomechanical properties of the bone-implant interface are important factors for implant performance. For further understanding of the osseointegration process novel tools enabling analysis of the intact interface in high resolution is needed, preferably combined with histology and biomechanical tests.
