Magnetically soft powder materials based on the Fe-Si-Al system

The magnetic properties, structure, and distribution of elements in powder alloys of the Fe-Si-Al system are studied. The concentration nonuniformity of the distribution of silicon and aluminum in the stage of sintering is determined after the introduction of alloying additives in the form of ferroalloys. The components forming a liquid phase in the stage of sintering and reducing the concentration sensitivity of the magnetic properties are chosen in order to create a powder sendast. Acomparative analysis of the properties of the fabricated and commercial alloys is made. __________ Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 3, pp. 23–26, March, 2006.
