摘要：
The microstructure and chemical characteristics of nanocrystalline NiAl intermetallic phase with a B2 crystalline structure are studied. Nanophase NiAl powder with the addition of minor elements (Fe, Ga and Mo) was prepared by mechanical alloying under argon atmosphere. Structural characterization based on X-ray diffraction (XRD) patterns and transmission electron microscopy (TT-M) observations were carried out on the NiAl compounds. The effects of the different microalloyed elements on the microstructure are explored. (C) 2002 Elsevier Science B.V. All rights reserved.
