| Abstract: | The magnetic properties of a mischmetal-cobalt alloy are studied. A mischmetal-64% cobalt alloy was melted in induction furnace
under a protective atmosphere of argon. The melt was solidified in a magnetic field of 7 kOe, and cooled to a temperature
of 950° C and was thereafter quenched in water. Specimens of suitable dimensions were machined, heat-treated in the temperature
range 1000–1100° C for various lengths of time and the magnetic properties evaluated. The (BH)max value was 10·3 MGOe which was associated with aB
r value of 7 kG and Hc value of 5 kOe. The results obtained offer feasibility to design new MM-Co5 magnets through developments in processing technique. |
