摘要	The microstructure of a multiphase Ni60Al25Cr15 intermetallic alloy was examined by optical microscope and TEM. It is noticed that a single phase gamma' layer was sandwiched between NiAl and ductile gamma/gamma' phases. The observation of fracture surface suggested that a weak interface between brittle beta-NiAl and gamma' phase be responsible for its low ductility. It was also determined that the brittle-to-ductile transition for this material is sensitive to strain rate and associated with lattice diffusion in NiAl phase. (C) 1999 Elsevier Science B.V.
