Latest Patents

One of his latest patents is titled "Metal alloy mass for forming in the semisolid state." This invention describes a metal alloy mass with a defined porosity for forming in the semi-solid state. The porosity is measured by cooling in ambient air from a temperature corresponding to a liquid fraction ratio between 30 and 70% to the ambient temperature. The mass achieves a porosity ratio, measured by image analysis, between 2 and 20%, and preferably between 3 and 8%. Additionally, when the gassing level is measured by a solidification test under 80 hPa, the mass has a volumetric porosity ratio between 3 and 50%, ideally between 4 and 25%.

Another significant patent is the "Method and apparatus for lubricated forward extrusion with radial." This invention relates to a method and apparatus for lubricated forward extrusion of metals and alloys, featuring radial forward removal of an outer shell or sheath. The method involves forming a gap in the shape of a plane or slightly truncated cone-shaped circular outer ring with a constant thickness and span, open to the atmosphere between the end of the container and the assembly of extrusion tools. To facilitate the formation and extraction of the outer shell, the extrusion apparatus includes several knives positioned in the described gap, which divide the outer shell into multiple 'petals' during extrusion.
