Latest Patents

Qingfu Chen holds a patent for an invention titled "Ultrafine-grained profile of twin-crystal wrought magnesium alloys, preparation process and use of the same." This patent describes a process that begins with the smelting and casting of magnesium alloy raw materials. The materials undergo solution treatment at temperatures ranging from 300 to 500 °C. A preform is then pre-deformed to create a substantial amount of twin crystal microstructure within the magnesium alloys, achieving a grain size of not larger than 100 μm. Following this, a continuous Equal Channel Angular Pressing (ECAP) process is performed at temperatures between 200 and 350 °C, allowing for the desired profile to be obtained. The resulting ultrafine-grained magnesium alloys exhibit grain sizes from 100 to 450 nm, tensile strength between 300 and 400 MPa, and elongation of 20 to 35%. The length of the profile can exceed 10 meters, making it suitable for continuous production.
