Description
Summary:Experimental design performed with the Statgraphics XVI Centurion software is used to optimize the magnetic hysteretic properties of an anisotropic hard magnetic Fe–30Cr–14Co powder alloy. The following magnetic hysteretic properties are reached: the remanence is B r = 1.24 T, the coercive force is H cB = 50.7 kA/m, and maximum energy product is ( BH ) max = 35.5 kJ/m 3 . Regression equations of the dependences of B r , H cB , and ( BH ) max on the heat treatment parameters of the alloy are derived and adequately describe the dependences within the phase space within variation ranges of selected parameters. The reached level of magnetic hysteretic properties of the alloy is almost identical to that of one of the most widely used industrial alloys, namely, YuNDK24 (GOST 17809–72) [1], although the cobalt content in the alloy under study is lower by more than 40%.
