Chromium‐rich oxide whiskers and nodules formed on the surface of an internal pore in additively‐manufactured stainless steel, as discussed in article number 1700102 by Brad L. Boyce and co‐workers. This internal porosity, caused by incomplete fusion of the source powder, results in low tensile ductility. The oxidation is thought to occur when porosity that connects to the free surface is exposed to the atmosphere during heat treatment.
