Computational modeling of electroslag remelting processes

Journal de Physique IV, 2004
Alloys used for the production of rotating components in aeroengines and land-based turbines are subject to stringent requirements to ensure absence of melt-related defects such as inclusions and segregation. Accordingly, the production of the superalloys alloys used in these applications involves multiple remelting stages, each of which plays a ...

Segregation of Niobium During Electroslag Remelting Process

Journal of Iron and Steel Research International, 2009
Experiment was carried out after the process parameters were calculated by the model previously established. The relationship between interdendritic spacing and local solidification time (LST) mainly determined by process parameters was exposed. Furthermore, the extent of segregation was studied. The results indicate that LST and interdendritic spacing
