| 1 | A detailed study of metallic glass formation in copper-hafnium-titanium alloys显示文摘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 mm.In order to improve the glass forming ability (GFA) getting even larger dc,the prevailing approach is to use complex multicomponent systems.This strategy has been investigated by us for the Cu-Hf-Ti bulk glass forming alloy Cu55Hf25Ti20 using >1 at.pct additions of B,Y,Nb,Ta,Al,Mn,Si or V but with no significant improvement in the GFA.Clearly,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 space.Thus,CuxHfyTiz alloys,where x=(40-70) at.pct,y=(5-30) at.pct,and z=(10-36) at.pct,were prepared by melt spinning andcopper mould suction-casting.The 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. | Ignacio A.Figueroa Sandro Baez-Pimiento John D.Plummer Omar Novelo-Peralta Hywell A.Davies Iain Todd | 2012 | Acta Metallurgica Sinica(English Letters)2012，25，6： | 2 |
