摘要：

Glass formation by ball milling of a mixture of intermetallic phases with composition Zr60Al10Ni9Cu18Co3 was investigated by X-ray diffraction and thermal analysis and compared with glassy phases produced by liquid undercooling and ball milling of an elemental powder mixture of same composition. The so obtained amorphous phase reveals a distinct glass transition and a large stability range of the highly undercooled melt of 95 K. It is believed that this is by far the widest temperature range of a highly undercooled melt found for ball milled amorphous materials. (C) 1997 Elsevier Science B.V.
