1. 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
2. Critical Aspects of Delubrication and Sintering of Chromium-alloyed Powder Metallurgy Steels
Sammanfattning : The cost efficiency and performance of Powder Metallurgy (PM) steels can be improved by replacing conventionally used alloying elements such as copper and nickel with chromium. Utilizing chromium imposes a challenge in terms of processing due to its effect on powder compressibility and high oxygen affinity, the latter of which, to a certain extent, is dealt with by introducing chromium in prealloyed form that decreases its activity.
