Metastable nanocrystalline nickel-boron alloys obtained by mechanical alloying

Abstract

Ni-B and Ni-Nb-B alloys are produced by mechanical alloying of mixtures of Ni, Nb, and B powders. X-ray diffraction analysis of the alloys indicates the formation of Ni(B) and Ni(Nb, B) solid solutions with nanocrystalline structure. The phase composition of the alloys is studied at different stages of mechanical alloying, along with the thermal stability and the phase transformations on heating.
