Abstract
En 中文
Investigating the synergistic effects is important for understanding the roles of the alloying elements and designing new kinds of superalloys. Understanding the dislocation mechanism is crucial for elucidating the Re-W synergistic strengthening effect in nickel-based single crystal superalloys. In this work, the interaction between clusters and dislocations was investigated using interrupted tensile tests combined with transmission electron microscopy (TEM) characterization. The results show that Re-W clusters hinder the motion of dislocations, trigger double cross-slip and promote the formation of dislocation tangles. This process enhances both the strength and the work hardening of the alloy.
