Problems solved by technology

[0002] Bulk amorphous alloy refers to an amorphous alloy material that reaches the millimeter level on a three-dimensional scale; in 1934, German physicist Kramer obtained an amorphous film by vapor deposition. Excellent mechanical properties, physical and chemical properties, wear resistance and corrosion resistance and good processing performance; nickel-based amorphous alloys also have high magnetic permeability and low-loss soft magnetic properties, nickel-based amorphous alloys are widely used in industrial fields; At present, most amorphous alloys are in the form of thin films, filaments, strips and powders, which greatly limits the application of amorphous alloys. Therefore, it is urgent to explore new methods for preparing bulk amorphous alloys.

Embodiment Construction

[0052] The present invention will be further described below in conjunction with accompanying drawing:

[0053] figure 1 As shown, the state diagram of vacuum hot pressing sintering of nickel-based bulk amorphous alloy, the position of each part must be correct, prepared according to the quantity, and operated in sequence.

[0054] Quantities of the chemical substances and materials used in the preparation are determined according to a preset range, with grams, millimeters, and milliliters as measurement units.

[0055] Vacuum hot-press sintering of nickel-based bulk non-gold alloy is carried out in a vacuum hot-press sintering furnace, which is completed in a vacuum state, plasma discharge heating, and pressure application;

[0056] The vacuum hot pressing sintering furnace is vertical. The upper part of the vacuum sintering furnace 1 is the furnace cover 2, the lower part is the furnace base 3, the furnace support 4, and the furnace chamber 34; The upper part is provided w...

Abstract

The invention relates to a preparation method of nickel-based bulk amorphous alloys. The method is characterized by comprising the steps of taking nickel-based amorphous thin strips as raw materials in allusion to the situation that bulk amorphous alloys are difficultly prepared, preparing dies, assembling the dies, carrying out hot pressing and sintering in vacuum to prepare the nickel-based bulk amorphous alloys; the prepared nickel-based bulk amorphous alloys are high in strength and high in density which reaches 99.8%; the preparation method is advanced in process and accurate and detailed in data, and is used as an advanced method for preparing the nickel-based bulk amorphous alloys.

Description

technical field [0001] The invention relates to a method for preparing a nickel-based bulk amorphous alloy, which belongs to the technical field of preparation and application of amorphous alloys. Background technique [0002] Bulk amorphous alloy refers to an amorphous alloy material that reaches the millimeter level on a three-dimensional scale; in 1934, German physicist Kramer obtained an amorphous film by vapor deposition. Excellent mechanical properties, physical and chemical properties, wear resistance and corrosion resistance and good processing performance; nickel-based amorphous alloys also have high magnetic permeability and low-loss soft magnetic properties, nickel-based amorphous alloys are widely used in industrial fields; At present, amorphous alloys are mostly in the form of thin films, filaments, strips and powders, which greatly limits the application of amorphous alloys. Therefore, it is urgent to explore new methods for preparing bulk amorphous alloys. ...
