Conclusions
-
1.
In magnico alloys carbon favors the development of the high-temperature β2→α+β2-decomposition and this decomposition has a negative effect on the magnetic properties of the alloys.
-
2.
The magnico alloys can be characterized by the hardenability, which is understood as the diameter of a cylindrical magnet ensuring the absence of the β2→α+β2-transformation after quenching. The hardenability of the magnico alloys increases with decreasing carbon concentrations.
-
3.
We obtained good magnetic properties in magnets of small cross section containing up to 0.05% C.
