Patent number: 11673192Abstract: The invention belongs to the field of amorphous alloys, and more specifically, relates to a method for calibrating the internal temperature field of amorphous alloy prepared by spark plasma sintering. First, the part required for temperature field calibration inside the bulk amorphous alloy sample obtained by spark plasma sintering is cut into a series of small amorphous alloy samples, and the isothermal crystallization treatment is performed to obtain the crystallization time of different parts of the sample. An annealing-isothermal crystallization experiment is performed on the adopted amorphous alloy powder at different annealing temperatures, and the functional relationship between the annealing temperature and the crystallization time is obtained.Type: GrantFiled: April 6, 2021Date of Patent: June 13, 2023Assignee: HUAZHONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Pan Gong, Huaping Ding, Xinyun Wang, Junsong Jin, Lei Deng, Mao Zhang, Xuefeng Tang

Patent number: 11154951Abstract: The invention belongs to the field of additive manufacturing of amorphous alloy, and discloses a laser 3D printing forming system of amorphous alloy foil and a forming method thereof. The unnecessary material of the amorphous alloy foil is cut by a first laser and then the remaining portion is selectively scanned and heated by a second laser so that the amorphous alloy is heated to be in a superplastic state in the supercooled liquid region. Then, the amorphous alloy foil is rolled by a preheated roller in combination with the ultrasonic vibration to achieve interatomic bonding between layers of the amorphous alloy foil, and the amorphous alloy foil is then rapidly cooled, so that an amorphous alloy part with a large size, a complicated shape and a porous structure is formed.Type: GrantFiled: March 23, 2018Date of Patent: October 26, 2021Assignee: HUAZHONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Pan Gong, Fangwei Li, Xinyun Wang, Jianhua Mo, Lei Deng, Junsong Jin
