21. Role of nanopowder as sintering aid in the densification of water atomized ferrous powder
Sammanfattning : Press and sinter powder metallurgy (PM) steels are cost-effective solutions for structural applications. There is a constant drive for the improvement in the density of these PM steels which helps in expanding their usage in applications demanding higher performance than what they deliver today. LÄS MER
22. 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
23. Processing Methods for Reaching Full Density Powder Metallurgical Materials
Sammanfattning : Powder metallurgy (PM) is one of the most cost effective methods for manufacturing structural components with complex shapes. Utilisation of the metal powder to shape the components allows to minimise material waste and increase energy efficiency. LÄS MER
24. Sintering of cemented carbides : experiments and modeling
Sammanfattning : During sintering of cemented carbides large volumetricshrinkage takes place. About half the volume of the originalgreen body is lost during this process. Due to lotal densitydifferentes within the green body undesired shape changes mayalso occur during sintering. LÄS MER
