1. Key Aspects of Sintering Powder Metallurgy Steel Prealloyed with Chromium and Manganese
Sammanfattning : The powder metallurgy (PM) process is a cost efficient near net-shape technology suitable for sustainable manufacturing of structural steel components. A drawback with the PM technology is the difficulty to use oxidation sensitive alloying elements, such as Cr and Mn. LÄS MER
2. Microanalysis of a ferritic steel intended for high temperature applications
Sammanfattning : .... LÄS MER
3. Studies of surface treatments of stainless steel for improved corrosion resistance
Sammanfattning : .... LÄS MER
4. Corrosion and Surface Studies of Stainless Steel and Chromium Carbide Thin-Films
Sammanfattning : Although the passive films that form on stainless steels have been extensively studied, the concentration depth profiles are not fully understood. Their thinness makes passive films hard to study, but angle-resolved X-ray photoelectron spectroscopy (ARXPS) is a non-destructive technique that can be used to obtain depth information. LÄS MER
5. Studies of oxide reduction and nitrogen uptake in sintering of chromium-alloyed steel powder
Sammanfattning : The powder metallurgy (PM) process route is very competitive for mass production of structural steel components with complex shape, due to efficient material utilisation, low energy consumption, and short overall production time. The most commonly used alloying elements are the processing friendly metals Cu, Ni and Mo. LÄS MER
