Method for making metallic glass and device for making the same

Abstract

A method and device for making metallic glass includes a first step of preparing metal or alloy; a second step of melting metal or alloy into liquid metal; a third step of putting the liquid metal into a boiler and applying pressure into the boiler and the liquid metal being ejected into lines from an outlet located a the lower portion of the boiler; a fourth step of cooling the lines as ejected from the outlet of the boiler in a cooling tank by a quick-flowing coolant; a fifth step of forming straight metallic glass fibers and allowing the metallic glass fibers to be settled to the bottom of the cooling tank; a sixth step of weaving the metallic glass fibers into pieces, and a seventh step of overlapping the pieces into a metallic glass. The lower portion of the boiler is located at a lower level than a surface of the coolant as quickly flowing in the cooling tank.

Claims

1. In a method for making metallic glass, comprising the following steps: A. preparing a metal or alloy to be melted; B. melting said metal or alloy into a liquid metal; C. putting the liquid metal into a boiler, applying pressure into the boiler and ejecting the liquid metal into lines through an outlet located at a lower portion of the boiler; D. cooling the lines as ejected from the outlet of the boiler in a cooling tank by a quick-flowing coolant; E. forming straight metallic glass fibers, allowing the metallic glass fibers to be settled to the bottom of the cooling tank; F. weaving the metallic glass fibers into pieces, and G. overlapping the pieces into a metallic glass; the improvement which comprises that: the lower portion of the boiler is located at a lower level than a surface of the quick-flowing coolant in the cooling tank.

2. The method as claimed in claim 1, wherein a speed that the coolant flows is faster than an ejecting speed of the liquid metal.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows the device of the of the present invention when manufacturing the metallic glass fibers, and

(2) FIG. 2 shows the steps of the method of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(3) Referring to FIG. 1, the device of the present invention comprises a boiler 1 and a cooling tank 2. The boiler 1 has an outlet 10 located at the lower portion thereof. The cooling tank 2 is filled with coolant 20 which flows at fast speed. The lower portion of the boiler 1 is located at a lower level than a surface of the coolant 20 as quickly flowing in the cooling tank 2.

(4) As shown in FIG. 2, the method for making metallic glass of the present invention comprises the following steps:

(5) A. preparing melting metal of alloy, such as Titanium based, Magnesium based, copper based and Iron based metal or alloy;

(6) B. melting metal or alloy into liquid metal 3;

(7) C. putting the liquid metal 3 into a boiler 1, applying pressure into the boiler 1 and ejecting the liquid metal 3 into the lines through an outlet 10 located at a lower portion of the boiler 1;

(8) D. cooling the lines as ejected from the outlet 10 of the boiler 1 in a cooling tank 2 by a quick-flowing coolant 20, wherein a speed that the coolant 20 flows is larger than an ejecting speed of the liquid metal 3 to prevent the line of the liquid metal 3 form being curved;

(9) E. forming straight metallic glass fibers 30, allowing the metallic glass fibers 30 to be settled to the bottom of the cooling tank 2;

(10) F. weaving the metallic glass fibers 30 into pieces, and

(11) G. overlapping the pieces into a metallic glass.

(12) The method of the present invention is able to make the metallic glass of different sizes, especially for making the larger size of the metallic glasses.

(13) The liquid metal 3 is cooled before being crystallized so as to form the metallic glass fibers 30 which are flexible and durable. The metallic glass fibers 30 are woven into pieces and the pieces are then overlapped to form a metallic glass. The metallic glass can be made into different sizes as needed. These metallic glasses have high stiffness, high strength, flexibility, extensibility, magnetic features, and are durable to wear and corrosion. The metallic glasses can be used to make portable electronic devices, space products, medical products and exercise products.

(14) While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
