Abstract
Official abstract text for this publication.
Disclosed is a high-elasticity aluminum alloy which contains carbide to improve elongation. Further, a method of manufacturing the high-elasticity aluminum alloy is provided. The method includes steps of: charging pure aluminum and an Al-5B master alloy in a melting furnace to form a first molten metal; charging an Al-10Ti master alloy in the first molten metal to form a second molten metal; charging silicon (Si) element in the second molten metal to form a third molten metal; adding carbon (C) to the third molten metal to form a fourth molten metal; and tapping the fourth molten metal into a mold to cast the fourth molten metal.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing an aluminum alloy, comprising steps of: charging pure aluminum and an Al-5B master alloy in a melting furnace to form a first molten metal; charging an Al-10Ti master alloy in the first molten metal to form a second molten metal; charging silicon (Si) element in the second molten metal to form a third molten metal; adding carbon (C) to the third molten metal to form a fourth molten metal; and tapping the fourth molten metal into a mold to cast the fourth molten metal, wherein the aluminum alloy comprises titanium (Ti) in an amount of about 4 to 6 wt %; boron (B) in an amount of about 0.5 to 1.5 wt %; silicon (Si) in an amount of about 10 to 12 w %; carbon (C) in an amount of about 0.3 to about 0.5 wt %; a balance of aluminum; and inevitable impurities, wherein the aluminum alloy includes carbide in an internal tissue thereof, wherein the aluminum alloy includes Al 3 Ti less than the carbide on a basis of weight %.
