- Title
A Study of the Causes of Failure of Permanent Magnets from Cast Hard Magnetic Alloys.
- Authors
Kamenskaya, N.; Sein, V.; Zvereva, M.
- Abstract
The microstructure and magnetic properties of permanent magnets fabricated from cast hard magnetic alloys of the Fe - Ni - Al system with cobalt addition of type YuNDK are studied. The causes of failure of such magnets in operation are determined. Recommendations are given for correcting the melting process and the modes of heat treatment of magnets in order to provide the required properties without disturbing the integrity of the magnets.
