From a chemistry perspective, this data helps clarify the mechanism behind the formation of various phases. CONCLUSION To summarize, many techniques can be used for phase analysis. Often, more than one technique could be used for the same material. The decision regarding which technique is best for the application depends on the material being evaluated and the nature of the phases present including their size, chemical composition, crystal structure, and volume fraction. Understanding the kind of information that can be derived from a given technique is of great importance. If the material being studied has large phases (around 10 microns) and can be etched to generate a contrast, the simpler optical microscopy and scanning electron microscopy combination would be appropriate. However, if the phase present is in the form of precipitates that are only a few tens of nanometers in size, then transmission electron microscopy and atom probe tomography are a better combination for phase analysis. ~AM&P For more information: Rajan Bhambroo, materials engineer, Tenneco Inc., 47001 Port St., Plymouth, MI 48170, 734.254.8229, rajan.bhambroo.18@ gmail.com.
