STUDY OF TOTAL OXYGEN CONTENT AND （总氧含量和研究）

STUDY OF TOTAL OXYGEN CONTENT AND OXIDE COMPOSITION FORMED DURING WATER ATOMIZATION OF STEEL POWDERS DUE TO MANGANESE VARIATION Master Thesis 2012 Due to confidential reasons some portions of this report have been removed. Contact Mr. FREDRIK PERSSON (Fredrik.s.Persson@) Global Process Development, Höganäs AB, 263 83 Höganäs, Sweden for further details. Krishnan Hariramabadran Anantha Department of Material Science and Engineering Royal Institute of Technology (KTH) SE-100 44 Stockholm Abstract Powder metallurgy (PM) is a technology used to manufacture near net shape components for an increasing number of applications like automobile components, aircraft components, cutting tools, refractory, household appliances, etc. The general PM process comprises of Powder manufacturing/powder tailoring, Compacting, and Sintering. Based on product’s final requirements, optional secondary operations are performed. PM components for automotive application are experiencing a growth coupled with new challenges. PM´s capability for producing complex net shaped components with desired properties has enabled it to be an alternative to other traditional manufacturing processes. Average U.S. made vehicle in 2010 contained an estimated 41.6 pounds of PM parts and in Europe, the average per vehicle PM parts in 2010 is estimated 18.5 pounds [3]. New design goals set by OEMs (original equipment manufacturers) demands for compl
