Microscopy techniques for additive manufacturing
The use of microscopy techniques for the advancement of additive manufacturing (AM) technology is presented. Such advancement can be realized by minimizing build defects, whilst promoting desired microstructures. With a focus on refractory high entropy alloys (RHEAs), a multiscale outline of techniques such as atom probe tomography, electron microscopy and X-ray analysis is presented. Their application to characterise the feedstock, as well as defects, chemical segregation and residual stress in the build is discussed.

Abstract
The use of microscopy techniques for the advancement of additive manufacturing (AM) technology is presented. Such advancement can be realized by minimizing build defects, whilst promoting desired microstructures. With a focus on refractory high entropy alloys (RHEAs), a multiscale outline of techniques such as atom probe tomography, electron microscopy and X-ray analysis is presented. Their application to characterise the feedstock, as well as defects, chemical segregation and residual stress in the build is discussed.
