Optimization of the Heat Treatment of a Hard Magnetic Fe–30Cr–16Co–1Sm Powder Alloy
The optimization of heat treatment of an anisotropic hard magnetic Fe–30Cr–16Co–1Sm powder alloy is performed by experimental design using the Statgraphics and Statistica software. After optimization, the remanence is Br = 1.252 T, the coercive force is HcB = 53.08 kA/m, and maximum energy product is (BH)max = 36.8 kJ/m3. Adequate regression equations of the dependences of Br, HcB, and (BH)max on the heat treatment parameters (holding time during isothermal thermomagnetic treatment (ITMT), cooling rate from the ITMT temperature to 580°C, and cooling rate from 580 to 500°C) within variations of selected parameters in corresponding phase spaces are obtained. The studied magnetic hysteretic properties of the Fe–30Cr–16Co–1Sm alloy exceed those of one of the most widely used commercial alloys, YuNDK4 (GOST 17809–72) [1], by more than 40% at a lower cobalt content.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
