from the work of CACCIAMANI et al[12]. Combining Eqn.(4) with the above thermo- dynamic description, the solidification path and the phase fraction can be calculated. 3 Results and discussion 3.1... alloys: (a) Al-5Mg-0.1Er; (b) Al-5Mg-0.7Er; (c) Al-4.5Mg-0.4Er. 3.2 Solidification path The solidification of Al-5Mg-0.1Er alloys was simulated by SCHEIL model, and the calculated solidification......
时间, 还要考虑凝固路径的影响. 关键词: 凝固路径; 显微偏析; 数值模拟 中图分类号: TG111.4 文献标识码: A Simulation on influence of solidification path on microsegregation parameters in Al-4.5%Cu alloy LIU Yong-gang1, CHEN Guang1, SUN..., Southeast University, Nanjing 210096, China) Abstract: Effects of solidification path on microsegregation parameters after solidification at different locations in the ingot of Al-4.5%Cu alloy were......
ternary eutectic solidification-path is taken as example, i.e. the corresponding liquid concentrations can be calculated by the following equations for each corresponding solidification stage... under the assumed different solidification conditions. It can be seen from Fig. 1(a) that the solidification path of the Scheil model is (L→α)→(L→α+Si)→(L→α+Si+Mg2Si), while the solidification paths under......
, the content of Si atoms in the liquid phase near the solid/liquid interface increases with cooling rate increasing. Therefore, the solidification path moves from line OS to line OF with the cooling rate increasing as described in Fig.6. Thus, the binary Al-Si eutectic transformation temperature decreases. Fig.6 Schematic illustration of solidification path 5 CONCLUSIONS 1) Increasing Mg......
