Nanocrystalline A13Ni, NiA1 and Ni3A1 phases in the Ni-AI system and the c~,/7, 7 and e phases in the Cu-Zn system were synthesized by mechanical alloying of elemental blends in a planetary mill. In the as-milled state, A13Ni and AINi were always ordered, while Ni3A1 was disordered. MA results in a

The nanocrystalline NiAl intermetallic compound was synthesized by mechanical alloying of the elemental powders. The structural changes of powder particles during mechanical alloying were studied by X-ray diffractometery, scanning electron microscopy and microhardness measurements. The mechanical al
AbstractΓThe synthesis, microstructural characterization and microhardness of nanocrystalline B2-phase NiAl intermetallic are discussed in this paper. Nanophase NiAl powders were prepared by mechanical alloying of elemental Ni and Al powders under an argon atmosphere for dierent times (0Β±48 h). The
