to a decreased glass forming ability, but with plasticity of 1.0%, the fracture strength of Fe71Mo2Nb3P12C10B2 alloy increases up to 4.0 GPa. The improvement of the fracture strength is discussed in terms of the enhancement of atomic bonding nature and the favorite formation of a network-like structure due to the substitution of Nb for Mo. Key words: Fe-(P, C)-based bulk metallic glass; Nb; forming ability......

Glass-forming Ability and Corrosion Resistance of Zr-Cu-Al-Co Bulk Metallic GlassW.Zhou,W.P.Weng,J.X.HouShagang School of Iron and Steel, Soochow University摘 要:Investigations were carried out to examine the effects of Co addition on the glass-forming ability(GFA)and corrosion resistance of Zr46Cu46(Al)8 bulk metallic glass in chloride-containing......
., Mexico Received 20 April 2017; accepted 28 September 2017 Abstract: The glass forming ability, thermal and mechanical properties of some ZrCuAlNi bulk metallic glasses were analyzed. The compositions..., of the experimentally obtained glasses indicated high glass forming ability. The glassy compositions showed a fragility index of ~40 GPa. The compression test of the investigated alloys was carried......
">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......
) Beijing Asahi Glass Electronics Co., Ltd., Beijing 100015, China摘 要:The structure of V2O5-P2O5-Sb2O3-Bi2O3 glass and its state of crystallization were studied by means of infrared spectroscopy and X-ray diffraction analysis. The results indicate that, in this glass, V and P exist mainly in the form of a single-stranded linear (VO 3 ) n and an isolated (PO 4......
