Embodiment Construction

[0027] In order to make the above and other purposes, features, and advantages of the present invention more obvious and understandable, the preferred embodiments of the present invention are specifically cited below, and are described in detail in conjunction with the accompanying drawings as follows:

[0028] The preferred embodiment of the present invention is an aluminum alloy with a nanocomposite phase, which is mainly composed of aluminum metal Al, manganese metal Mn and magnesium metal Mg, which contains 1.1% to 7.0% of manganese and 0.1% to 6.0% of magnesium in weight percentage And the rest is made up to 100% by aluminum, which increases the use of low-cost manganese. The invention provides improved toughness through the aluminum metal; improves the hardness of the aluminum alloy through controlling the addition amount of the manganese metal; and improves the strength and corrosion resistance of the aluminum alloy through controlling the addition amount of the magnesiu...

Abstract

Al alloy with composite nano phase and its use are both disclosed herewith. It contains (wt%): Mn 1.1-7.0, Mg 0.1-6.0, Sc 0.01-1.5, and balanced with Al. The Mn and Mg and Sc make Al slender cylindrical nano phase formed in Al alloy to improve its physical and chemical performances.

Description

technical field [0001] The present invention relates to an aluminum alloy with a nano-composite phase and its application, in particular to adding a specific proportion of scandium element to the manganese-magnesium-aluminum alloy to promote the formation of an aluminum alloy with a nano-composite phase of a long cylinder. Background technique [0002] Traditional aluminum alloys adopt four digits according to the number identification system of the American Aluminum Association [Alumium Association]. The first digit represents the alloy system, and there are 1, 2, 3...9 alloy systems; the second digit Represents the number of improvements of the alloy, which can be 0, 1, 2, 3... etc.; the third and fourth digits are the old numbers of the Aluminum Company of America, Alcoa. As shown in Schedule 1. [0003] Table I [0004] Numbering Main alloying elements added 10XX Pure aluminum (above 99%) 20XX Cu 30XX mn 40XX Si ...
