- Аннотация: Abstract: (Sm,Zr)(Co,Cu,Fe)6.0–6.8 alloys are prepared by vacuum induction melting and subsequently subjected to heat treatment in order to form a high-coercivity state, which includes annealing at 1160–1180°C for 5 h, quenching to room temperature, isothermal aging at 800°C for 20 h, and subsequent stepped tempering from 800 to 400°C at an average cooling rate of 100°C/h. The morphology and composition of main structural constituents of the alloys are studied by electron microscopy using samples in the form of individual grains separated from ingots. The hysteretic properties of the (Sm,Zr)(Co,Cu,Fe)z samples in the high-coercivity state are shown to correlate with the volume fractions of their main structural constituents, which, in turn, are controlled by the ratio of the 4f-/4d-/3d-element contents in the chemical composition of the alloy. © 2022, Pleiades Publishing, Ltd.
