Effects of carburization on recrystallization behavior of a single crystal superalloy

Influence of deformation temperature on recrystallization in a Ni-based single crystal superalloy

“…One of the possible sources of the necessary plastic deformation before heat treatment is contraction stress during directional solidification, and the strains can be introduced at different temperatures [3,4] ranging from ambient temperature to elevated temperatures. However, most of the previous work on RX of SX superalloys focuses on the influence of annealing conditions [5], orientational dependence [6], microstructural features [7,8], and mechanical properties [2]. Little work has been conducted on the influence of deformation temperature on the RX of SX superalloys.…”

Simulation and Experimental Study of Recrystallization Kinetics of Nickel Based Single Crystal Superalloys

“…There are only 3 independent constants in [S]. By the spatial geometry transformation, the Young's modulus E' and shear modulus G' in a given crystallographic orientation can be obtained as follows: 11 11 Fig. 1 shows Young's modulus in all orientations at 980 C and 1070 C, which confirms high anisotropy of SX superalloy DD6.…”

“…Most of previous work on recrystallization of SX superalloys focuses on annealing conditions [2,[9][10], microstructural features [11] and mechanical properties. Xie et al [12] investigated the orientational dependence of deformation and recrystallization in a Ni-based single crystal superalloy.…”

The deformation and the recrystallization initiation in the dendrite core and interdendritic regions of a directionally solidified nickel-based superalloy

“…Considerable work has been done on recrystallization (RX) due to its detrimental effect on the mechanical properties of directionally solidified (DS), especially single crystal (SX) superalloys [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. More attention has been paid to the effect of RX on the mechanical properties [1][2][3][4][5][6][7], the modeling of RX process [8], RX mechanisms [9][10][11][12][13] and the way to reduce or eliminate RX [14,15].…”
