Crystallographic Orientation Influence on the Serrated Yielding Behavior of a Single-Crystal Superalloy

Since Ni-based single-crystal superalloys are anisotropic materials, their behavior in different crystal orientations is of great interest. In this study, the yielding behavior in both tension and compression for , and oriented materials at 500 °C has been investigated. The direction showed a serrated yielding behavior, a great tension/compression asymmetry in yield strength and visible deformation bands. However, the and directions showed a...
