Abstract

The effects of processing conditions and crystallographic orientation of growing dendrites on stray grain formation were investigated in welds of single crystal Ni-based superalloys. The degree of constitutional supercooling (CS) at the solidification front were used as a metric to quantify the effects. The results showed an appreciable effect of dendrite orientation on CS.
