Abstract : A primary objective of this research has been to test and refine a model to describe the metallurgical behavior of Sm(Co,Fe,Cu,Zr) alloys and the complex relationships between the compositions, heat treatments, microstructures and compositions of the phase observed, and the corresponding magnetic properties developed by the alloys. A second objective was to develop laboratory techniques and procedures for the processing of 2:17 type permanent magnet in order to be reasonably confident that observed variations in the magnetic and other physical properties measured would reflect intentional changes in compositional and heat treating parameters. A third objective of developing higher energy product 2:17 type permanent magnets than were known at the beginning of the research effort was not accomplished.
