Abstract

The dislocation structure changes of Ni-based single crystal superalloy in the heat affected zone were investigated. X-ray Laue diffraction and electron microscopy show that alternating dislocations slip systems dominate in the HAZ. The orientation at each position of the crystal was precisely determined by an automated indexing program. The results show that the maximum value of the thermal gradient is observed in the heat affected zone near the fusion line.
