Abstract:

Development of temperature compensated magnets was undertaken in both 217 and NdFeB type of alloys. A number of alloys have been identified that can produce energy product in excess of 40 MGOe in the uncompensated material. Computer programs were developed for identifying key compositions that were then processed successfully into temperature compensated magnets. Current materials can produce temperature compensated magnets with an energy product not exceeding 22 MGOe. Further work is necessary to develop temperature compensated magnets with an energy product exceeding 30 MGOe.
