Abstract:

A process has been developed whereby single crystals of incongruently melting intermetallic compounds between rare earth and iron group transition elements can be grown and fabricated into small spheres. Single crystals of YCo5, NdCo5, DyCo5, and YFe9 have been grown, and spheres up to 2.67 millimeters in diameter have been fabricated from these materials with the exception of DyCo5. Metallographic techniques were developed for these materials, and in many cases the results differed substantially from published data. Metallographic and x-ray techniques were used to establish the single crystal character of the materials. Author
