- The quantitative particle concentration can give important information about the cleanliness of melts for quality control in primary and secondary production of aluminum. Manual quantification of the particle concentration is normally a time consuming process and human control can bias the acquired images and particle count. The present paper explains the automated image-processing steps for the quantification of SiC-particles, with equivalent diameters from 2 to 25 μm, in solidified A356.
