Abstract

Microstructural evolution of recrystallization (RX) grains of single-crystal (SX) alloy DD6 was studied experimentally, and then X-ray investigation was carried out. The results showed that the cellular recrystallization (CRX) occurred when the grit blasted specimens were heat treated at 1100 °C, while the equaixed recrystallization (ERX) and mixed recrystallization (MRX) were found at 1300 and 1200 °C, respectively. The pole density distributes extremely non-homogeneously for SX alloy, while the pole density distribution demonstrates homogeneously for CRX due to the existence of a large number of CRX grains with different orientation in the SX alloy. The pole density distribution of MRX is comparable with CRXs, while the difference of pole density distribution is obvious between ERX and CRX (or MRX).
