Abstract null null Detailed three-dimensional (3D) microtomography characterizations of inclusions in electrode matrix, mushy zone (MZ) and liquid melt film (LMF) were performed to elucidate the motion and removal behavior of inclusions in electrode tip during magnetically controlled electroslag remelting (MC-ESR) process. A transient 2D numerical model was also built to verify the experimental results and proposed mechanisms. The number and size of inclusions exhibited an obvious increasing tre...

Abstract Magnetic-controlled Electroslag Remelting (MC-ESR) process has been proposed to improve the inclusion removal efficiency in recent years. In this study, the effects of transverse static magnetic field (TSMF) on liquid melting film (LMF) and inclusion removal during this period in ESR process of GCr15 steel were studied by a series of MC-ESR experiments. The thickness of the characteristic position of LMF was reduced by 27.2%∼80.5% when a 65mT TSMF was applied. The number and size of the...

The effects of an axial static magnetic field (ASMF) on the carbides and mechanical properties of electroslag-remelted (ESR) Cr12MoV die steel were investigated. The superimposition of a 30 mT ASMF induced unidirectional rotation in the molten slag pool, resulting in a more uniform temperature distribution at the front of the dendrite solid–liquid interface. The size of the grains and carbides in the ESR Cr12MoV steel ingot became smaller. The sulfur content of the ingots decreased and the mecha...

Abstract Zr-1Nb alloy performs desired corrosion resistance in deionized water but shows accelerated corrosion in lithiated water. However, the degradation mechanism of Zr-1Nb alloy in lithiated water is still unclear. In this work, blister-like morphologies on the oxide film of the Zr-1Nb alloy corroded in lithiated water was observed, providing a direct evidence to the hydrogen generation beneath the oxide film. The formation of blisters was analysed from the perspectives of blister morphology...

Electroslag remelting (ESR) is an effective method for removing nonmetallic inclusions from steels or alloys. The main stage of inclusion removal during ESR is the aggregation of liquid metal film (LMF) to form droplets at the consumable electrode tip. In this study, a lab-level ESR experiment was carried out. The number and size of inclusions at the characteristic position of the electrode were quantitatively counted. The number of inclusions in the center position of LMF were larger than that ...

β-Nb is a typical second phase in Zr–Nb-based alloys used as fuel claddings in water-cooled nuclear reactors. The segregation of alloying element Fe may affect the corrosion resistance of Zr–Nb-based alloys. In this work, the Fe segregation at the interface between β-Nb phase and α-Zr matrix in Zr–2.5Nb alloy was studied using atom probe tomography and focused ion beam. The results suggested that the Fe concentration was much lower than Nb concentration in α-Zr matrix, while Fe selectively segre...
