specific Embodiment approach 1

[0011] Specific Embodiment 1: In this embodiment, the preparation of amorphous alloy needles is carried out according to the following steps: the master alloy is placed in an inert atmosphere with a pressure of 0.02-0.07 MPa for arc melting, and then the master alloy melt is formed by copper mold suction casting. The amorphous alloy needle is obtained; the master alloy is Zr 51 Cu 24.22 Ni 14.06 Al 10.72 , Fe 36-45 co 2-5 Cr 15 Mo 14 C 15 B 6 Y 1-5 、Cu 44-54 Ti 30-38 Zr 6-12 Ni 6-9 、Ti 40 Zr 25 Ni 3 Cu 12 be 20 、Ti 40-45 Zr 2-5 f 4-6 Cu 37-43 Ni 7 Si 1 sn 0-9 or Ni 40-42 Ti 22-27 Zr 20-26 Al 7-9 Cu 5 Si 2-6 .

[0012] In conjunction with Fig. 1 and Fig. 2, the copper mold suction casting method of the present embodiment is illustrated: the master alloy melt is sucked in the metal copper mold cavity 2 of the amorphous alloy needle (the cavity 2 is composed of the left lobe mold 1 and the right lobe mold of the metal copper mold). The valve mold 3...

specific Embodiment approach 2

[0017] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the master alloy is arc-melted in an inert atmosphere with a pressure of 0.05 MPa. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0018] Embodiment 3: The difference between this embodiment and Embodiment 1 is that: vacuumize first and then fill with inert gas to form an inert atmosphere. Others are the same as in the first embodiment.

Abstract

The invention relates to a method for preparing amorphous alloy needles and relates to a method for preparing alloy needles. The invention solves the problem that an existing method for preparing needle products easily leads the products to appear that the mechanical property, the microstructure, non-metallic inclusions and the like are not accord with the requirements. The method of the invention for preparing the amorphous alloy needles comprises following steps: arranging master alloy into the inert atmosphere whose pressure is 0.02-0.07MPa to weld with electric arcs, then, adopting a water-cooled copper mold method by the master alloy to shape, and obtaining the amorphous alloy needles. The method of the invention for preparing the amorphous alloy needles is simple and the amorphous alloy needles which are prepared have excellent performance.

Description

technical field [0001] The invention relates to a method for preparing an alloy needle. Background technique [0002] Various types of needle products need to be widely used in fields such as textiles and medical treatment. Currently, the raw materials used are steels such as carbon tool steel, which contain harmful elements such as sulfur; and the preparation methods of existing needle products need to Raw materials are subjected to high-strength machining, which causes the current needle products to be prone to problems such as physical and mechanical properties, microstructure, and non-metallic inclusions that do not meet the requirements. In addition, the existing method for preparing needle products requires repeated machining and sharpening, which is inefficient and has large tolerances for products of the same type. Contents of the invention [0003] The present invention provides a method for preparing amorphous alloy needles in order to solve the problems that th...
