Abstract
The magnetic properties and certain physical properties of sintered iron-cobalt-molybdenum alloys have been investigated, and a study made of the effect of processing variables, i.e. particle size, compacting pressure, sintering temperature and time. The compacting and sintering conditions which result in optimum properties have been determined. Consideration is also given to the influence on magnetic properties of variations in heat-treatment procedure, involving such factors as quenching temperature and media, ageing time and temperature, &c.
The substitution of ferro-molybdenum powder for elemental molybdenum powder reduces the cost of raw materials substantially without greatly diminishing the magnetic properties. Commercial powders with a normal particle-size distribution give good properties.
It was found that the alloys had somewhat better qualities than those made by casting.
