Product prepared from amorphous alloy and heterogeneous material and preparation method thereof

Abstract

The invention provides a product prepared from amorphous alloy and heterogeneous material, and a preparation method of the product. The product prepared from amorphous alloy and heterogeneous material comprises a core body prepared from the heterogeneous material, and an outer wall, wherein the outer wall is prepared from the amorphous alloy coating the outer surface of the core body; and the critical dimension of the amorphous alloy is larger than or equal to 1mm. The product has the advantages of high yield strength, high hardness, high elasticity, high abrasion resistance, high corrosion resistance, and low manufacture cost, thereby improving the applicability of the amorphous alloy.

Description

technical field [0001] The present invention relates to an article formed of amorphous alloy and heterogeneous material and its manufacturing method. Background technique [0002] Amorphous alloy materials, also known as metallic glasses, have excellent physical and chemical properties, such as high yield strength, high hardness, and superelasticity, which are different from ordinary crystalline metal materials due to the unique arrangement structure of atoms that make up the alloy. (high elastic limit), high wear resistance, high corrosion resistance, etc., so it is considered to have broad application prospects. [0003] Initially, amorphous alloys were difficult to be practically applied due to their small critical size. Recently, the critical size of amorphous alloys has gradually developed from micron to millimeter or even centimeter. Usually, the critical cooling rate is lower than 500°C / s, and the critical Amorphous alloys with a size greater than 1 mm are called bul...

AI Technical Summary

Problems solved by technology

[0004] Although amorphous alloys have the above unique performance advantages and forming advantages, currently amorphous alloys usually contain precious metals in order to obtain a high critical size, which has a high material cost, which limits its wide application, especially in large parts application in

For example, although the critical size of Pd-based, rare-earth-based, and zirconium-based amorphous alloys is as high as centimeters or more, the high material cost is daunting; although copper-based and magnesium-based amorphous alloys have relatively reduced cost of host elements, due to Usually contain a large amount of precious elements such as silver, beryllium, cobalt, rare earth, etc., but the material cost is still relatively high
