1. Key Aspects of Sintering Powder Metallurgy Steel Prealloyed with Chromium and Manganese
Abstract : The powder metallurgy (PM) process is a cost efficient near net-shape technology suitable for sustainable manufacturing of structural steel components. A drawback with the PM technology is the difficulty to use oxidation sensitive alloying elements, such as Cr and Mn. READ MORE

2. Surface Characteristics of Water Atomized Pre-alloyed Steel Powders and their effect on Sintering
Abstract : Powder Metallurgy (PM) is an efficient method, in terms of cost and raw material utilization, for the production of structural parts that have strict dimensional tolerances and complex geometries. In the common processing route, steel powder is fabricated by water atomization and then pressed and sintered into the final component. READ MORE

3. Surface Chemical Characteristics of Chromium-alloyed Steel Powder and the Role of Process Parameters during Sintering
Abstract : Powder Metallurgy (PM) is a cost efficient method suitable for sustainable production of structural parts that have strict dimensional tolerances and complex geometries. It has been a common practice to utilize Ni and Cu as alloying elements in PM steels, but the high and fluctuating prices of Ni and the concerns around it associated with health hazards as well as the difficulty in recycling Cu lead the PM industry to search for effective alternatives such as Cr and Mn.

5. Sintering in the Kraft Pulp Mill - Studies in the Rotary Kiln and Recovery Boiler
Abstract : The conversion of black liquor to white liquor is carried out in the chemical recovery system, which is made up of several units; in two of them, i.e. the recovery boiler and the rotary kiln, sintering plays an important role. READ MORE
