High spatial resolution mapping of precipitates in novel alloys.
The CAMECA EPMA are widely utilized to support the developement of novel alloys. Applying low accelerating voltages (down to 5 keV) with intense beam currents in the SXFive-TACTIS, the electron-sample interaction volume is reduced, and high spatial resolution can be achieved with high X-ray count rates.
X-ray maps of novel Zr-Al-Ti alloys were acquired at 7 keV / 100 nA, wich makes it possible to observe the variation of interface composition around the precipitates, enabling understanding of their formation processes.
