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…

Since the appearance of the first California-type models around 1940, the profilograph has been a popular device used for quality control in the construction of pavements. Both roadway and airfield landing agencies have adopted roughness indexes computed from profilograph-derived measurements as a level of construction quality. Emerging high-speed inertial profilers can now quickly collect…
