6. Fundamental studies on the high temperature corrosion mechanisms of a 22Cr austenitic stainless steel in environments related to oxy-fuel combustion
Sammanfattning : This thesis concern the high temperature corrosion mechanisms of stainless steels, with focus on a 22 wt.% Cr FeNiCr alloy (Sanicro 25), in environments related to oxy-fuel combustion, which is a promising technology that can provide enhanced CO2 recovery and sequestration from power plants by using post-combustion capture.

7. Microstructure of a cubic boron nitride tool material and its degradation during hard turning operations
Sammanfattning : Abstract. Polycrystalline cubic boron nitride (PCBN) materials are widely used in turning operations of hardened steels due to their beneficial mechanical properties like maintained high hardness at elevated temperatures, adequate toughness and for being more chemically stable towards iron compared to diamond at temperatures typical for turning operations.

8. Surface Characteristics of Water Atomized Pre-alloyed Steel Powders and their effect on Sintering
Sammanfattning : Powder Metallurgy (PM) is an efficient method, in terms of cost and raw material utilization, for the production of structural parts that have strict dimensional tolerances and complex geometries. In the common processing route, steel powder is fabricated by water atomization and then pressed and sintered into the final component. LÄS MER
