Abstract

The formation of accumulated misorientation during directional solidification of Ni-based single-crystal superalloys with 〈001〉 direction deviating from cylinder axis by 20 deg was investigated at different withdrawal rates. The accumulated misorientation increased from the converging side of the dendrite with respect to the mold wall to the diverging side in the radial direction. With increased solidification distance, the accumulated misorientation in the solidification direction reached 7.6 deg, and was not significantly affected by withdrawal rates.
