Adsorption-extraction mechanism of heavy rare earth by Cyanex272-P507 impregnated resin LIAO Chun-fa(廖春发), JIAO Yun-fen(焦芸芬), LIANG Yong(梁 勇), JIANG Ping-guo(姜平国), NIE Hua-ping(聂华平) School... of saturation, equimolar series change and slope were applied to study the extraction mechanism of Cyanex272-P507 impregnated resin for heavy rare earths from hydrochloric acid solution. The results show......
on the microstructure and mechanical properties of Al-8.2%Zn-2.1%Mg-2.3%Cu based alloys are scarce, and its refinement mechanism is still not clear yet[14]. In this paper, the relationship between the mechanical behavior and microstructure characteristics of Al-Zn-Mg-Cu based alloys with and without Sc and Zr is investigated to understand the mechanism of grain refining and dispersive precipitation. 2......

of the sample, and the γ′ phase is transformed into the rafted structure along the direction vertical to the applied stress axis in the regions far from the fracture. But the coarsening and twisting extents of the rafted γ′ phase increase in the regions near the fracture, which is attributed to the occurrence of the larger plastic deformation. In the later stage of creep, the deformation mechanism......
