Competitive deformation induced by TCP precipitation and creep inconsistency on dendritic structures in a nickel-based single crystal superalloy crept at high temperatures
Wanshun Xia,Xinbao Zhao,Quanzhao Yue,Weidong Xuan,Qing Pan,Jiangwei Wang,Qingqing Ding,Hongbin Bei,Ze Zhang +8 more
TL;DR: In this article , the authors investigated the creep properties of a 4th generation nickel-based single crystal superalloy (Ni-SX) at 1150 and 1100 °C and revealed the competitive microcrack initiation induced by topologically close-packed (TCP) phase formation and creep inconsistency on dendritic structures showing the strong temperature and time dependent relations.

Effects of Mo addition on microstructure of a 4th generation Ni-based single crystal superalloy
TL;DR: In this article , the effects of Mo addition on the microstructure of a 4th generation Ni-based single crystal superalloy were investigated, and it revealed that the primary and secondary dendrite arm spacings were barely affected by Mo addition.

Homogenizing effects of Co on multi-scale elemental distribution in Ru-containing Ni-based single crystal superalloys
TL;DR: In this article , the effects of Co on multi-scale elemental distributions were studied in an advanced Ru-containing Ni-based single crystal superalloys, where the large-scale dendritic segregations and smallscale elemental partitions between γ/γ' phase were compared in as-cast, heat-treated and thermal-exposed alloys.

The nucleation of δ phases triggered by the stacking faults in a single crystal superalloy
Yuan Cheng,Xinbao Zhao,Quanzhao Yue,Wanshun Xia,Qing Pan,Yu Zhou,Yuefeng Gu,Ze Zhang +7 more
TL;DR: Stacking faults in a Ni-based single crystal superalloy at 800°C trigger δ phase nucleation, with Ru having a more significant promoting effect than Re, influencing alloy design and phase transformation.

The role of Mo on the creep deformation of a 4th generation Ni-based single crystal superalloy at 1100 °C
Yuan Cheng,Xinbao Zhao,Quanzhao Yue,Qing Pan,Jiachen Xu,Wanshun Xia,Yuefeng Gu,Ze Zhang +7 more
TL;DR: Mo addition to a 4th generation Ni-based single crystal superalloy at 1100 °C affects creep properties, with 2-3 wt% Mo optimal, while excessive Mo (>3 wt%) degrades performance due to TCP phase precipitation and dislocation slip resistance decrease.
