Solidification of Mg-28%Zn-2%Y alloy involving icosahedral quasicrystal phase WAN Di-qing(万迪庆), YANG Gen-cang(杨根仓), ZHU Man(朱 满), XU Quan(许 泉), ZHOU Yao-he(周尧和) State Key Laboratory of Solidification Processing, Northwestern Polytechnical University, Xi’an 710072, China Received 16 May 2006; accepted 23 January 2007 ......
and duration decreased to almost zero after carbon inoculation. The grain refining efficiency of carbon inoculation could be assessed by the shape of the cooling curve and solidification...], interaction between addition elements [20,21] and optimizing refiner and modifier level in a foundry [22,23]. The precise shape of the cooling curve is directly related to the solidification......

(2016) 23: 10-17 DOI: 10.1007/s11771-016-3043-y Analysis of 13Cr bloom solidification structure using CA-FE model ZHAI Ying-ying(翟莹莹)1, MA Bei-yue(马北越)1, LI Ying(厉英)1, JIANG... 2522, Australia Central South University Press and Springer-Verlag Berlin Heidelberg 2016 Abstract: Solidification structure is critical in the control of the mechanical properties and quality during......
Effect of liquid-liquid structure transition on solidification of Sn-Bi alloys ZU Fang-qiu(祖方遒), ZHOU Bing(周 兵), LI Xian-fen(李先芬), YI Xun(益 汛), CHEN Yi-ping(陈轶平), SUN Qi-qiang (孙其强) College...) on the solidification behaviors and morphologies of Sn-Bi alloys was studied further. The results show that the undercooling of the primary and eutectic phase increases and the microstructure becomes finer after......
J. Cent. South Univ. (2019) 26: 1856-1862 DOI: https://doi.org/10.1007/s11771-019-4139-y A new slope optimization design based on limit curve method FANG Hong-wei(方宏伟)1,2, CHEN Yohchia(陈幼佳)3,4... Abstract: A new method is proposed for slope optimization design based on the limit curve method, where the slope is in the limit equilibrium state when the limit slope curve determined by the slip-line......
to power function form which is the same to that in Ref. [22]. Figure 1(a) shows the calculated solidification paths and Fig. 1(b) shows the temperature vs solid fraction curve of Al-2Si-3Mg alloy... the other four conditions finished on the binary trough (L→α)→(L→α+Si). It can be also seen from the temperature vs solid fraction (T-fS) curve shown in Fig. 1(b) that only the solidification path......
