Figure 1a: Energy-filtered TEM image; and Figure 1b: 3D atom probe reconstruction of gamma prime precipitates in the nickel base superalloy Rene 88. The atom probe reconstruction in (b) shows A1-rich regions, corresponding to the gamma prime phase, as wh
An example of coupling of energy-filtered transition electron microscope, or TEM (Figure 1a) with atom probe tomography (Figure 1b) to investigate different generations of gamma prime precipitates, at multiple length scales, in the nickel base superalloy, Rene 88, used in turbine disk applications. Figure 2a shows coupling of high-resolution TEM (a) with atom probe tomography (b and c) to study the atomic scale structure and composition of nanoscale omega precipitates in a titanium-molybdenum alloy.
