  • 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.

  • Patent number: 10724126
    Abstract: The present invention relates to a high hardness amorphous composite, a method of preparing the high hardness amorphous composite and application thereof. The high hardness amorphous composite includes a basic alloy component, a hard additive and a bonding additive. The basic alloy component includes 45-60 mole % Zr, 5-10 mole % Hf, 5-15 mole % Al, 8-22 mole % Ni and 6-14 mole % Cu, the hard additive is ZrC or WC nanometer powder with addition amount at 12-26 wt % of the basic alloy component, particle diameter of the WC nanometer powder is 10-100 nm, and the bonding additive is any one or two selected from groups of Re, W or Mo with addition amount at 4-8 wt % of the basic alloy component. The high hardness Zr-based amorphous composite with good workability and formability is provided by improving composition of alloy based on Zr—Al—Ni—Cu, adding new component and adjusting component content.
