Elementally characterizing intermetallic compounds (IMCs) to identify phases has routinely required relatively expensive transmission electron microscopy (TEM) analysis. A study was done characterizing IMCs using less expensive energydispersive x-ray (EDX) spectroscopy tools to investigate it as a practical alternative to TEM. The study found that EDX line scanning can differentiate phases by tracking changes in count rate as the electron beam of a scanning electron microscope (SEM) passes from one phase to another.
