  • Patent number: 10751792
    Abstract: A continuous precision forming device and process for an amorphous alloy is provided. By means of the device, when a melting platform with an alloy melt is rotated from the melting position to a position just below the forming mould (9), temperature of the alloy melt can be in the range of the overcooled liquid zone temperature of the alloy melt, and then a loading rod (7) drives the forming mould (9) to proceed with pressing forming. According to the process, press-forming is carried out in a certain temperature interval in the amorphous alloy melt solidification process, and the heating, cooling, solidification and forming in the forming process are coordinated, such that continuous forming of the amorphous alloy is achieved.
