Title: Innovations by James W. Knight
Introduction
James W. Knight is a notable inventor based in Davison, MI (US), recognized for his contributions to the field of metallurgy and materials science. He holds a total of four patents, showcasing his innovative approach to solving complex problems in high-pressure die casting.
Latest Patents
One of his latest patents is a "Method to determine skin-layer thickness in high pressure die castings." This quantitative metallographic method measures skin layer thickness in high-pressure die cast aluminum components. The faster-cooling skin layer region exhibits a higher volume fraction of eutectic phases compared to the slower-cooling inner region. By obtaining images at various thicknesses of a location of interest in a cast component sample using an image analyzer, he can determine eutectic volume fractions. These measurements can then be compared against known or predicted quantities for specific alloy compositions, allowing for the correlation of skin layer thickness.
Another significant patent is the "Method for automatic quantification of dendrite arm spacing in dendritic microstructures." This method automatically quantifies dendrite arm spacing in dendritic microstructures. Once a location of interest in a cast material specimen is identified, the information is analyzed to quantify dendrite cell size, which is then converted into quantified dendrite arm spacing through empirical or theoretical relationships. This method accounts for non-equilibrium conditions, particularly in scenarios where the casting cools rapidly during solidification.
