摘要：

The mechanochemical reaction has been applied to synthesizing nano-sized amorphous Cu40Zr60 ahoy particles. The structure of Cu-Zr particles has been investigated by means of X-ray diffraction, transmission electron microscopy and differential thermal analysis. The tests show that the amorphous Cu-Zr particles are around 40 nm in size. The crystallization temperature of the nano-sized amorphous Cu40Zr60 particles is lower than that of the corresponding micron-scale particles. The formation mechanism of the nano-sized amorphous Cu40Zr60 alloy particles is also discussed. (C) 1998 Elsevier Science S.A. All rights reserved.
