摘要：
The magnetic properties and the changes in the domain structure of alloy Sm(Co, Fe, Cu, Zr)(7.5) are studied after different variants of heat treatment, i.e. (1) quenching from 1200 degrees C with cooling in a helium jet; (2) quenching and tempering at 800 degrees C for 16 h, cooling at a rate of 50 K/min to room temperature; and (3) quenching, tempering at 800 degrees C for 16 h, and cooling at a rate of 1.7 K/min. The influence of the heat treatment modes on the coercivity and the domain sizes is determined. The mechanism of variation of these characteristics is analyzed.
