Advanced Techniques for Improved Properties of P/M Ferrous Soft Magnetic Materials

Deepika Sharma

Powder Metallurgical (P/M) route of manufacturing has its inherent advantages such as the utilization of the material to a greater extent, ability to get the product in net shape without subsequent machining or incorporating any other additional forming operation. At the same time, P/M processing makes it possible to tailor the magnetic properties of a part to suit a specific application by effectively controlling the powder characteristics, material’s chemistry and processing parameters. Thus P/M processing offers the material and product designer a wide flexible range and a greater scope for material’s development. The desired magnetic properties in P/M soft magnetic materials may be obtained by selecting appropriate alloy chemistry and optimizing the processing parameters. The requirement of high density is a predominant factor for improving the performance of powder metallurgy components employed in soft magnetic applications. Also, new methods are being developed by modifying the existing ones for the production of P/M parts to improve performance, efficiency and life of the components and to make them suitable in a wider range of applications. Most of these methods are of commercial importance and many of them have been patented.
