“…It has also been shown that the large field of view in LEAP allows for analysis of larger features, such as whole transistor devices. 8 As mentioned above, in the conventional 3-DAP field evaporation is generated by nanosecond high voltage pulses. This requires a high degree of conductivity of the specimen, which has been one of the major limitations of the technique since it only allowed for studies of metals and highly doped semiconductors.…”

Two complementary techniques for the characterisation of the fine scale microstructure of materials are briefly described: three-dimensional atom probe (3-DAP) analysis and energy filtered transmission electron microscopy (EFTEM). The 3-DAP is especially suited for the characterisation of clustering and of the chemistry and size of very small precipitates, in particular when several phases are present. Energy filtered transmission electron microscopy is useful for determining size, volume fraction and number density of precipitates in the approximate size range 20-200 nm, also when several phases are present. As examples of the usefulness of a combination of these techniques, results from two types of complex martensitic steels are reviewed: the sequence of precipitation in a high strength maraging steel, Nanoflex, and the microstructure of creep resistant 9-12%Cr steels.
