The Three‐Dimensional Morphology of Topologically Close Packed Phases in a High Rhenium Containing Nickel Based Superalloy

The three-dimensional morphology of topologically close packed phases (TCP) in an experimental 6 wt% rhenium-containing superalloy is examined with focused ion beam tomography and compared to the existing knowledge gained with classical microscopy of two-dimensional cross-sections. The results show completely new insights compared to investigation of cross-sections. With the new technique, three different types of TCP-phase morphologies and the...
