Benefits of technology

The present invention is a method of improving the elasticity of an aluminum alloy by maximizing the formation of a boride compound and adding CNT. This results in a highly elastic aluminum alloy. The technical effect of this invention is improved elasticity of aluminum alloy.

Problems solved by technology

For example, when only silicon (Si) is used to make a high elastic alloy, the elasticity of the alloy cannot be sufficiently improved, and the silicon (Si) particles become coarse.
As such, it is difficult to produce a highly elastic alloy because of the coarse silicon (Si) particles.
Further, conventional aluminum (Al) composite materials are expensive, even though they are formed into powder using reinforced metal compounds or carbon nanotubes (CNTs).
Further, when powdered reinforced particles are introduced into a casting process, there are problems of loss, wettability and dispersity in a molten aluminum (Al) solution.
This results in causing several problems, including increased cost, increase difficulty in control over the process and the like.
However, this technology does not solve the above problems of loss, wettability and dispersity in a molten aluminum (Al) solution when powdered reinforced particles are introduced into a casting process.
Further, when the amount of reinforced particles is increased, this technology does not adequately decrease costs, process control difficulty or the like.

Abstract

Disclosed is an aluminum alloy, including: about 14˜20 wt % of Si; about 2˜7.5 wt % of Ti; about 1˜3 wt % of B; and a balance of Al as a main component, wherein wt % are based on the total weight of the aluminum alloy and wherein a ratio of Ti / B is about 2˜2.5:1.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims under 35 U.S.C. §119(a) the benefit of Korean Patent Application No. 10-2012-0145787 filed Dec. 13, 2012, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Technical Field[0003]The present invention relates to a high elastic aluminum alloy, particularly to such an alloy whose elasticity is remarkably improved by maximizing the formation of a boride compound and adding CNT thereto, and a method of manufacturing the same.[0004]2. Description of the Related Art[0005]Conventionally, in providing alloys, the various alloy ingredients are controlled so as to impart desired characteristics.[0006]For example, when only silicon (Si) is used to make a high elastic alloy, the elasticity of the alloy cannot be sufficiently improved, and the silicon (Si) particles become coarse. As such, it is difficult to produce a highly elastic alloy because of the coarse silicon (Si) partic...
