1. Alloy element redistribution during sintering of powder metallurgy steels
Sammanfattning : Homogenization of alloying elements is desired during sintering of powder metallurgy components. The redistribution processes such as penetration of liquid phase into the interparticle/grain boundaries of solid particles and subsequent solid-state diffusion of alloy element(s) in the base powder, are important for the effective homogenization of alloy element(s) during liquid phase sintering of the mixed powders.

2. The Atmospheric Corrosion of Magnesium Alloys : Influence of Microstructure and Environments
Sammanfattning : The low density and high specific strength of magnesium alloys have created a great deal of interest in the use of these alloys in the automotive and aerospace industries and in portable electronics. All of these industries deal with applications in which weight is extremely important. LÄS MER
3. A Process Integration Approach to Assessing Possibilities for Improved Material Efficiency in Nordic ore-based Iron- and Steelmaking Systems
Sammanfattning : Iron- and steel production is a material- and energy intensive industrial activity. The production of one tonne of steel commonly results in some 400 kilograms of residual materials such as metallurgical slags, dusts, sludge and scales generated in the processes. LÄS MER
4. Novel approaches for achieving full density powder metallurgy steels
Sammanfattning : Powder metallurgy (PM) is one of the most resource-efficient methods for manufacturing structural components with complex shapes. The utilisation of the metal powder to shape the components allows to minimise material waste and increase energy efficiency. LÄS MER
5. Delubrication of Chromium Prealloyed Powder Metallurgy Steels
Sammanfattning : Consolidation of steel components produced by means of powder metallurgy (PM) is achieved typically through compaction and sintering. During consolidation, final dimensions of the part are already achieved after compaction, while sintering imparts strength to the components. LÄS MER
