Characterization and comparison of single var-remelted and double var-remelted ingots of incoloy ® alloy

HIGHLIGHTS

• who: A. Ducoli from the Centre porosity and typical segregations of ingot casting are eliminated due to progressive melting and solidificationThe solidification structure of a VAR ingot depends on solidification rate and on temperature gradient at the interface. The direction of growth of the cellular dendrites is the same of the direction of the heat flow, which is always perpendicular to the solidification front. This brings to the formation of big central columnar grains perpendicular to the pool profile. Higher is the melting rate, deeper is the melting pool and, therefore, the grains grow tilt respect to . . .
