Predicting and validating the behavior of Additively Manufactured (AM) materials requires a good understanding of the underlying microstructure. The AM process makes a wide variety of microstructures, some of them are similar to their more traditionally manufactured counterparts. However, in the case of as-built AM 316L, the AM microstructure is much more complex than the traditional equiaxed 316L structure that is typically observed. We will show how EBSD serial sectioning can be used to characterize this complex structure by collection thousands of grains in an as-build AM 316L material, revealing true grain shapes, morphological and crystallographic neighbor correlations. These features will be related to the non-equilibrium solidification and rapid quenching process present during the AM process.
