“…To investigate this topic, a number of models [76][77][78][79][80] have been developed based on the force balance on the inclusion at the advancing liquid/solid interface. Meanwhile, Confocal Scanning Laser Microscopy (CSLM) has also been applied for in situ observation of the behavior of particles [47,[81][82][83][84]. Most models define a critical solidification velocity above which inclusions are engulfed.…”

Abstract:The formation of nonmetallic inclusions in the solidification process can essentially influence the properties of steels. Computational simulation provides an effective and valuable method to study the process due to the difficulty of online investigation. This paper reviews the modeling work of inclusion formation during the solidification of steel. Microsegregation and inclusion formation thermodynamics and kinetics are first introduced, which are the fundamentals to simulate the phenomenon in the solidification process. Next, the thermodynamic and kinetic models coupled with microsegregation dedicated to inclusion formation are briefly described and summarized before the development and future expectations are discussed.

“…If it has not been already engulfed by any of them, it will be entrapped in the last portion of the solidifying steel, most frequently in the ingot axis. The interaction of a particle with the crystallization front can be directly observed only on the liquid steel surface [1][2]. Depending on the chemical composition of the inclusion, its behavior differs in relation to the mobile solidification front.…”

This work deals the phenomenon interaction of crystallization front on the particles of non-metallic precipitates. The behavior of a single particle in the vicinity of horizontal and vertical front was analyzed. The forces acting on the particle were characterized and the equilibrium condition formulated, from which the critical velocity of front may be deduced. The calculation results were illustrated in the form of graphs.Keywords: solidification front, non-metallic inclusions, forcesPraca zajmuje się zjawiskiem oddziaływania przemieszczającego frontu krystalizacji na cząstki wydzieleń niemetalicznych. Analizowano zachowanie pojedynczej cząstki wydzielenia w pobliżu poziomego i pionowego frontu. Scharakteryzowano siły działające na cząstkę w pobliżu frontu i sformułowano warunek równowagi, z którego wynika szybkość krytyczna frontu. Wyniki obliczeń zilustrowano w postaci wykresów.

“…In the Ce-Al-O system, Wang et al [23] calculated the attractive force decreasing in the order of that Ce 2 O 3 , CeAlO 3 , and Al 2 O 3 . Although studies about the attractive force between inclusion particles are relatively extensive, [24][25][26] there is limited information available in the literature concerning the capillary force of Ce-O-S particles combined with in situ observation. In addition, the underlying causes that affected the agglomeration behavior of particles need to further study from the perspective of atomistic scale.…”

This paper aims to investigate the agglomeration behavior of cerium oxide particles at the interface of high‐temperature melts. The high‐temperature experiment with 0.15% cerium addition was carried out at 1600 °C and the type of cerium oxide was detected to be Ce‐O‐S particles according to thermodynamic calculation and energy dispersive analysis. The attractive force between particles was analyzed by high‐temperature confocal laser scanning microscopy and the Kralchevsky‐Paunov model. The in‐situ observation indicate that the largest acting distance between Ce‐O‐S particle pairs was measured to be 80 μm. The attractive force becomes weak as the distance between Ce‐O‐S particle pairs (L) decreases, and a stronger attractive force exists between Ce‐O‐S particle pairs with a smaller radius ratio (R1/R2). The capillary force for Ce‐O‐S particles is weaker than that for Ce2O3 particles. The first‐principles results indicate that the wettability at the interface of the Fe/Ce2O3‐S system is weaker than the Fe‐S/Ce2O3 system, which is in agreement with the in‐situ observation and Kralchevsky‐Paunov model results. Furthermore, the atomistic mechanism of agglomeration behavior is revealed.This article is protected by copyright. All rights reserved.
