Characteristics of Powder Metal for 3D Printing

Post by:

In Powder Metal (PM) applications such as 3D printing, the flow and packing behavior of PM is influenced by particle size and shape distributions. These properties can be measured in a statistically meaningful way using computer controlled scanning electron microscopy (CCSEM). In livetime, the SEM program detects a particle, defines its perimeter, calculates its size and […]

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 […]
