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 B_r, coercive force H_cB, 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%.

硬磁Fe-30Cr-16Co粉末合金热处理优化

摘要

使用 Statgraphics 和 Statistica 软件通过实验设计优化了硬磁 Fe-30Cr-16Co 粉末合金的热处理。该合金是使用国产粉末通过传统的粉末冶金程序制备的。优化使我们能够达到不含任何额外合金元素的三元合金的磁滞特性（剩磁B _r、矫顽力H _cB、最大能量积 ( BH ) _max），高于工业 YuNDK24 合金 (GOST) 的磁滞特性17809-71)，钴含量高出 30%。
