    Författare :Johan Wendel; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sintering; powder metallurgy; iron powder; dilatometry; surface analysis; thermal analysis;

    Sammanfattning : Various types of iron powder are extensively used in the powder metallurgy (PM) industry. Water-atomized iron powder is commonly used as the base in many low-alloyed steel products manufactured through the conventional 'press and sinter' route, while carbonyl iron powder is often used for metal injection moulded (MIM) components.

  3. 2. Sintering of water-atomized iron and low-alloyed steel powder

    Författare :Johan Wendel; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reduction kinetics; water-atomized steel powder; water-atomized iron powder; sintering; oxide reduction; surface analysis; dilatometry; surface chemistry; thermogravimetric analysis;

    Sammanfattning : Iron and steel powder grades are extensively used in the powder metallurgy (PM) industry for manufacturing of ferrous structural components, with a major customer in the automotive industry. The powder grades are predominantly manufactured by water-atomization, yielding powder particles with highly irregular morphology and good compressibility, making the powder ideal for the conventional press-and-sinter manufacturing route.
