Within this study, the normal spectral emissivity at melting and in the liquid state of the highly alloyed steel HS2-9-1-8 at 684.5 nm is presented. Measurements were performed with a division-of-amplitude photopolarimeter, as part of a fast ohmic pu

The present paper deals with the formation of macrosegregation in a benchmark ingot using (Fe-C-Cr) ternary alloy composition. The numerical investigation of complex multiphase phenomena is a difficult study, because the thermophysical properties dep

Strong temperature fluctuations might exist in non-isothermal turbulent flow. When a RANS approach is used for simulation it is necessary to time average all properties that are temperature dependant. Here we focus on the time average of the Joule he

Normal spectral emissivity measurements at 684.5 nm for two steels and two nickel-based superalloys at the melting transition and in the molten state are reported in this study. The measurements were performed using a division-of-amplitude photopolar

A mixed columnar-equiaxed solidification model is used to predict the macrosegregation in high grade steel ingots. In this model, three phases are considered: the melt; the columnar phase, which is assumed to be stationary; and the equiaxed phase, wh
