Understanding variability of metal additive parts

TESCAN Ga FIB-SEM LYRA3 used for preparation of electron-transparent TEM specimens

Understanding variability of metal additive parts

In this work, a Ni-Ti alloy is used as a sensory material in order to quantitatively, and rather rapidly, observe compositional and/or microstructural variability in selective laser melting manufactured parts. These results provide an important first step towards understanding the nature of variability in additively manufactured parts. The TEM specimens used in this study were prepared with the TESCAN Ga FIB-SEM LYRA3 using the standard lift-out method and thinned to electron-transparency at a low ion beam energy.
