Latest Patents

Ichikawa holds a patent for a method of manufacturing metallic materials with extremely fine crystal grains. This method involves taking molten metallic material from a melting chamber and introducing it into an agitation chamber. In this chamber, the material is agitated for 60 seconds or less using a screw-shaped stirring rod that rotates at 500 rpm or greater. The metallic material is then extruded in a state of solid-liquid coexistence from an extrusion nozzle and is quench-solidified immediately to maintain the fine crystal grains. The stirring rod can rotate at speeds between 800 to 1000 rpm, and the material can reside in the solid-liquid state for 5 to 60 seconds.
