摘要：

An in-situ NiAl/Cr(Mo)-Hf eutectic composite has been successfully fabricated using the Bridgman technique. The microstructure was analyzed using scanning electron microscopy (SEM) with energy disperse spectroscopy and transmission electron microscopy (TEM). The mechanical behavior of the composite, including compressive and tensile properties at room and elevated temperature, was studied. It was found that the strengths of the composite are higher than that of NiAl alloys. Subsequently, the mechanism of improving the strength was analyzed. (C) 2000 Elsevier Science B.V.
