  • High-efficiency optical limiter using metasurface and phase-change material
    Patent number: 11209716
    Abstract: According to some aspects, a transmissive and all-dielectric optical component/limiter with great cutoff efficiency using Vanadium Dioxide (VO2) as the active component is disclosed. In some embodiments, Vanadium dioxide is used for an optical limiter due to the large contrast in optical constants upon undergoing the semiconductor to metal phase transition. When triggered optically, this transition occurs within 60 fs, making the device suitable for an ultrafast laser environment. In addition, the phase transition threshold is tunable by applying stress or doping; therefore, the device cutoff intensity can be adjusted to fulfill specific requirements.

  • Continuous casting and continuous forging forming process for aluminum wheel
    Patent number: 10695828
    Abstract: Disclosed is a continuous casting and continuous forging forming process for an aluminum wheel. The process combines the advantage of low-pressure filling stability of molten aluminum alloy, and utilizes the strengthening effect of extrusion deformation forging of a side mold locking ring and a pressure module to improve the mechanical properties of an aluminum wheel material to close to the forging level. A mold cavity is sealed by means of the side mold locking ring and a center mold locking taper, and the extrusion forging pressure acts on the surface of the aluminum alloy in the closed mold cavity, so that the requirement of equipment for mold closing tonnage is lowered, and the cost of the equipment is far lower than that of forging equipment and equivalent to that of casting equipment.
