摘      要：Recently we have reported a number of bulk glass forming compositions in the CuHf-Ti system,with the critical thickness for complete glass formation,dc,ranging from 2 mm to 4 *** order to improve the glass forming ability （GFA） getting even larger dc,the prevailing approach is to use complex multicomponent *** strategy has been investigated by us for the Cu-Hf-Ti bulk glass forming alloy Cu55Hf25Ti20 using 〉1 *** additions of B,Y,Nb,Ta,Al,Mn,Si or V but with no significant improvement in the ***,it is necessary,in order to utilise the full potential of the base ternary system,to identify the best glass-forming compositions as a basis for extending the search into multi-dimensional compositional ***,CuxHfyTiz alloys,where x=（40-70） ***,y=（5-30） ***,and z=（10-36） ***,were prepared by melt spinning andcopper mould *** composition dependence of the GFA for the Cu-Hf-Ti alloys,as measured by dc for rod and ribbon samples,is reported over the composition range given above.
