ASTM grain size is a property written into many specifications for metals, with finer grain sizes generally indicating better mechanical properties, such as formability. While measuring certain materials for such properties can be difficult, electron backscatter diffraction can provide precise determinations as well as give information on grain size distribution and statistics. A new ASTM…
