“…2), emulsified at that temperature in the furnace, taken out of the furnace and cooled spontaneously outside of the furnace (the Al-matrix solidified within a 30 s).

“…The densities of these phases differ significantly (about 2.3 g/cm 3 for the Al-alloy and about 7.9 g/cm 3 for Cd [54]), thus the volumes of the two liquid phases have the ratio of about Al/Cd ¼ 6.0. Thus, the Cd-in-Al type emulsion is expected to form, what is proven already in [21].…”

“…This method would effectively retrain liquid phase segregation to obtain immiscible alloys with refined microstructure. Budai and Kaptay [21] and Nagy et al [22] presented the homogenous microstructure of Al-Cd alloys by in situ precipitating intermetallic Al 4 Sr compounds. The intermetallic precipitates prefer to exist at the Al-Cd interface and to stabilize the Cd droplets in the Al matrix.…”

Liquid phase segregation of immiscible alloys has been investigated for decades. In this work, rare-earth Ce was studied as an additive for Al-Bi immiscible alloys. The addition of Ce restrained liquid phase segregation to obtain a uniformly dispersive microstructure. The experimental results indicated that in situ-precipitated intermetallic CeBi 2 compound acted as an inoculant for the heterogeneous nucleation of the Bi-rich droplets. The Bi-rich droplets nucleated on the CeBi 2 compound surface-a homogenous dispersed microstructure obtained via a heterogeneous nucleation route. We concluded that gravity segregation can be suppressed by the addition of rare-earth Ce.

Aluminum matrix monotectic alloys with a homogeneous distribution of the second phase droplets can be obtained in large ingots, if the droplets are stabilized by solid particles of optimized wettability at the interface of the two, immiscible liquid metals. In this paper, Al‐matrix emulsions with Cd‐rich droplets, stabilized by Al4Sr intermetallic particles are prepared, based on our previous paper. The new information in the present paper is the development of a new type of a mixer, allowing increased rotational speed, and hence, more efficient emulsification without the danger of mixing the liquid metals out of the crucible. As the comparative experiments proved, the ratio of emulsified Cd‐rich liquid was found to increase considerably when the old mixer was replaced by the new one. Particularly, there is no 1‐phase Cd‐rich sedimentation found at the bottom of the crucible when the mixer of the new design is applied.
