6. Key Aspects of Sintering Powder Metallurgy Steel Prealloyed with Chromium and Manganese
Sammanfattning : 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. LÄS MER
7. 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
8. Processing Methods for Reaching Full Density Powder Metallurgical Materials
Sammanfattning : Powder metallurgy (PM) is one of the most cost effective methods for manufacturing structural components with complex shapes. Utilisation of the metal powder to shape the components allows to minimise material waste and increase energy efficiency. LÄS MER
9. Surface Composition and Microstructure Control during Pressureless Forming and Sintering of Ferrous Powder Metallurgy Materials
Sammanfattning : This study addresses key issues related to different stages of ferrous PM materials processing. Several analytical tools are applied in the study of surface composition and microstructure control in the processing of ferrous powder including forming, degassing and sintering stages. LÄS MER
10. On Surface Characteristics and Microstructural Development of Soft Magnetic Composite Powder and Components
Sammanfattning : Soft Magnetic Composite (SMC) products manufactured by traditional Powder Metallurgical (PM) techniques, are strong candidate materials for electromagnetic applications. Their advantages are based on cost and energy efficient production methods, shape complexity realization and uniquely uniform and isotropic three dimensional (3D) magnetic properties. LÄS MER
