Shell phase selection and layer numbers of core–shell structure in monotectic alloys with stable miscibility gap

Metastable monotectic phase separation in Co–Cu alloys

“…N. Wang et al [14] and C.P. Wang et al [15] studied phase selection characteristics of coreshell microstructures in two stable immiscible systems.…”

Fe-shell/Cu-core encapsulated metallic phase change materials prepared by aerodynamic levitation method

“…A core-shell structure would have formed in this case by other processing methods [8,12,19]. Instead, in the ADL processing, a two-concentric-layer structure formed in the kernel as shown in Fig.…”

“…At the same time, the liquid phase separation phenomenon of immiscible alloys has attracted much attention, and preparation of core-shell structure in immiscible alloys has been investigated intensively [8][9][10][11][12]. Through proper control of processing parameters, core-shell immiscible alloys with a low-melting-point (LMP) phase coated by a high-melting-point (HMP) phase can be applied as encapsulated metallic PCMs (EM-PCMs), since the LMP phase can absorb and release heat through melting and solidification as metallic PCMs with the HMP phase as the packaging material.…”

Liquid Phase Separation Mechanism of Cu‐40 wt.% Pb Hypermonotectic Alloys

“…However, the system always proceeded spontaneously in the direction of decreasing the free energy because these larger atoms were always squeezed to the surface and enriched on the surface to form positive adsorption. e surface tension of the whole [15]. system was reduced because of the large volume of these atoms and the low surface tension.…”

“…In hypermonotectic alloys with the composition range of 37.4-86%, the liquid phase separation phenomenon occurred above the monotectic temperature. erefore, in this study, the Cu-40 wt.% Pb hypermonotectic alloy was investigated, and its position in the phase diagram [15] was marked with the arrow (Figure 1). …”
