"There are all these thermal and kinetic processes occurring simultaneously during this process, and they lead to a very, very messy microstructure," she says. "You see defects like pores and irregularities in the atomic structure, which are typically considered to be strength-deteriorating defects. If you were to build something out of steel, say, an engine block, you would not want to see this type of microstructure because it would significantly weaken the material." However, Greer says they found exactly the opposite. The many defects that would weaken a metal part at a larger scale strengthen the nanoscale parts instead."
