EBSD for Crystal Particle Analysis

Post by:

The analysis of a material’s crystallographic properties can provide a researcher with a wealth of information, including the identification, processing history, and much more. Although many techniques can be used to obtain various pieces of information, electron backscatter diffraction (EBSD) can give a more complete picture of not only what the substance is, but what […]

Supporting Superalloys – A Unique Approach to Powder Metal Cleanliness

Post by:

Superalloys are nickel-based or cobalt-based alloys that are resistant to high temperatures, perform better, are corrosion and oxidation resistant, and last longer than other metals. Superalloy parts are traditionally produced from powdered metals (PM) using subtractive manufacturing techniques. These parts are most often used in heavy industry or in areas having a corrosive environment, as […]
