Embodiment 18

[0027] Use (Zr 54.4 f 0.4 Cu 29.9 Ag 0.3 Ni 5 Al 10 ) 99.5 Y 0.5 Alloy, induction melting 30kg, vacuum degree 10 -1 ~10 -2 Pa. Preparation of amorphous components by vacuum die-casting, heating temperature 900-1000°C, vacuum degree 10-10 -1 Pa, the alloy is reused 5 times, and the prepared components can still ensure the amorphous structure of the material. The prepared parts such as figure 1 shown. Repeatedly using the alloy four times to cast the φ5mm sample can ensure the formation of amorphous.

Abstract

The invention discloses a (ZrM)-(CuN)-Ni-Al-(Re) amorphous alloy which comprises the following components in percentage by atom: 40-65% of Zr, 18-46% of Cu, 2-15% of Ni, 4-15% of Al, 0.1-3% of M(Hf, Ti or Hf+Ti), 0.05-3% of N (Ag) and 0.1-2% of rare-earth element RE (Y, Gd, Sc, Er or composition thereof). By adding small amounts of M, N and RE elements on the basis of the Zr-Al-Ni-Cu amorphous alloy, the alloy has the advantages of higher amorphous formation capacity, excellent manufacturability and favorable mold resistance, maintains the excellent mechanical properties of the Zr-Al-Ni-Cu amorphous alloy, and is an ideal material for preparing complex thin-wall parts in the fields of consumer electronics, medical care, automobiles and the like.

Description

technical field [0001] The invention relates to the technical field of Zr-based amorphous alloy manufacturing, in particular to a (ZrM)-(CuN)-Ni-Al-(Re) amorphous alloy with high amorphous forming ability and manufacturability, its preparation and application. Background technique [0002] Due to its special structure, Zr-based amorphous alloy has many excellent properties, such as: high strength (1500-2000MPa), high hardness (about HRC 50), high elastic limit (about 2%), excellent corrosion resistance It has important application prospects in the fields of consumer electronics, medical and health care, aerospace and transportation. [0003] For Zr-based amorphous alloys, a variety of alloy components have been developed, such as the Zr-Ti-Cu-Ni-Be alloy system developed in the United States, with a critical cooling rate of 1K / s, strong amorphous formation ability, and manufacturable The ability is strong, but the existence of toxic element Be in the alloy system restricts ...
