Russian Metallurgy (Metally) Aims and scope

Abstract

The heat treatment of a hard magnetic Fe–30Cr–16Co powder alloy is optimized by experimental design using the Statgraphics and Statistica software. The alloy is prepared by a traditional powder metallurgy procedure using domestic powders. The optimization allows us to reach magnetic hysteretic properties (remanence Br, coercive force HcB, maximum energy product (BH)max) for the ternary alloy free from any additional alloying elements, which are higher than those for an industrial YuNDK24 alloy (GOST 17809–71) with a cobalt content higher by 30%.
