    Abstract : With a rising global demand for green energy production, hydropower plays a key role in securing a reliable and sustainable energy supply. Hydropower is the largest and most efficient renewable energy source, with an ever-increasing capacity. READ MORE

  4. 2. Delubrication of Chromium Prealloyed Powder Metallurgy Steels

    Author : Seshendra Karamchedu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alloyed sintered steels; delubrication; surface oxide; sintering atmosphere; processing atmosphere control; lubricant;

    Abstract : 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. READ MORE
