J. Cent. South Univ. (2012) 19: 312-318 DOI: 10.1007/s11771-012-1006-5 In-situ growth of silver nanostructure on quartz glass substrates YI Zao(易早)1, 2, ZHANG Jian-bo(张建波)1, NIU Gao(牛高)1, CHEN Yan(陈艳... Press and Springer-Verlag Berlin Heidelberg 2012 Abstract: Silver nanostructure compact aggregates on the surface of quartz glass substrates were synthesized by small gold seeds with the assistance......
strength of nickel based super-alloy at room temperature, the main forming method for thin-walled curved surface parts is hot-forming. The sheet metal plastic deformation ability makes the thin-walled...

of Ti40Zr25Cu12Ni3Be20 were prepared. The effect of the addition of yttrium at levels of 0.2 at.%, 0.4 at.%, 0.5 at.%, 0.6 at.%, and 1 at.% on the glass forming ability (GFA) of the alloy has been investigated by means of metallography, X-ray diffraction, and differential scanning calorimetry. Experimental data in-dicates that high impurity content dramatically reduces the glass forming ability......

) were proved to be changed from 672 K, 734 K, 62 K, 0.575 to 691 K, 752 K, 61 K, 0.592 and to 681 K, 729 K, 48 K, 0.590, respectively. The results indicate that the glass-forming ability (GFA... is the third kind of elements, which are different from other constituting elements, and there are a strong bonding and atoms size effects between constituting elements, which cause the glass-forming ability......
