Characterization of metals, ranging from large surfaces to inclusions and precipitates.

Modern cutting-edge metals are increasingly engineered at the nanoscale to enhance their durability, reliability, and cost. Even traditional processes are now augmented with microscopic inspection to determine the resulting material’s elemental and structural composition.
In particular, the effective production of metals requires precise control of inclusions and precipitates. Depending on their consistency and distribution, these can either strengthen the material or act as contaminants, greatly impacting quality and lifetime. These microscopic properties can include;
- Nano-precipitates formed during rolling, annealing or hot pressing
- Nanoscale morphological changes (dislocations, crack initiation sites)
- Grain boundaries
- Oxide inclusions that cause casting interruptions in steelmaking
Historically, researchers have used optical microscopy to rate the size and number of inclusions, but this method does not provide any elemental information. Even optical emission spectroscopy, which can determine the elemental ratios of inclusions, does not accurately characterize the shape and composition of individual inclusions. Electron microscopy techniques have also been used for metal analysis, with scanning electron microscopy (SEM) capable of visualizing larger oxide inclusions, whereas transmission electron microscopy (TEM) is generally required to study features smaller than 100 nm. TEM analysis, however, has previously required manual particle counting and analysis, limiting the amount of data that could be collected to several dozen particles per day.

Thermo Fisher Scientific provides a range of electron microscopy solutions that make metal analysis not only more informative but also far more rapid. Thanks to our unique automation capabilities, a thorough overview of the elemental and structural composition of hundreds, if not thousands, of precipitates is possible in a manner of hours, as compared to the few dozen that would be found in a day of manual analysis. Not only is statistical information on the bulk available, but individual precipitates can also be seen with high detail, providing a multi-scale overview of the metal.
Our robust, automated instruments can perform a variety of critical tasks including:
- Nanoparticle counting, particularly useful for steel and aluminum production where light weighting is a top priority
- High throughput chemical analysis with energy-dispersive X-ray spectroscopy (EDS) mapping
- Instantly showing composition gradients across the sample surface with scanning electron microscopy (SEM) via ChemiSEM technology
- Rapidly preparing large area transmission electron microscopy samples or 3D volumes with plasma focused ion beam (PFIB) milling
