Abstract
The structure of rapidly quenched Ni-B alloys with compositions in the range from 15 to 50 at. % B including some eutectic compositions has been studied by X-ray diffraction, metallurgical microscopy and electron microscopy. It is found by X-ray diffraction that amorphous alloys can be obtained for narrow concentration ranges near the eutectic compositions; (18.5-19 at. % B) and (38-40 at. % B). However, even for these compositions, a small amount of crystallites is present in the amorphous matrix. No indication of which crystalline phase (Ni, Ni3B or Ni2B) appears preferentially near the boundary between the amorphous and the crystalline phases is obtained by electron microscopic observation.
