Latest Patents

One of Seong Hoon Yi's latest patents is titled "Quasicrystalline phase-reinforced Mg-based metallic alloy with high warm and hot formability and method of making the same." This invention discloses a quasicrystalline phase-reinforced magnesium-based metallic alloy that exhibits high warm and hot formability. The alloy comprises a composition of Mg—1~10 at % Zn—0.1~3 at % Y, where a two-phase region consisting of a quasicrystalline phase and a magnesium-based solid solution phase exists. The Mg-based solid solution phase is formed as a primary solid phase upon solidification, while the quasicrystalline phase serves as a second phase, reinforcing the matrix structure. The materials obtained through hot rolling or extrusion of the cast alloy demonstrate significantly increased strength due to the enhanced volume percentage of the second phase.

Another significant patent by Yi is an "Apparatus for ventilating rooms preferably large premises." This apparatus is designed for ventilating spacious public rooms, workshops, industrial halls, and underground parking lots. It comprises a damper with multiple shutters attached to the inner surface of a tubular body, allowing for radial movement from a shut position to an opened position. Additionally, the apparatus includes a nozzle with guide vanes that create swirls in the jet of injected ventilation air. This design enables precise adjustment of supply air with minimal resistance, ensuring a non-turbulent flow and protection against undesirable thermal air streams.
