Problems solved by technology

[0031] In a word, the results obtained by summarizing the background technology are as follows: ① the design starting point is based on the invention that "can make the injection body deviate from the injection direction".
② There is no patent publication for the method of "adding Si by in-situ synthesis method"
③Although the above-mentioned 1971 U.S. Patent No. 3,556,872 discloses the addition of 0.1% mixed rare earths, there is no patent publication for adding rare earth Nd (neodymium) with a high melting point and individuality and in the form of Nd-Fe master alloy

Embodiment 1

[0094] Add 68g of metal magnesium with a purity of 99.5% in the steel crucible, that is, W Mg = 68g. Then pour the analytically pure liquid KCl equal to the weight of the added magnesium onto the surface of the magnesium block. Induction heating melts magnesium and maintains the temperature at 790°C±3°C, which is also the in-situ synthesis temperature, expressed as T I-S =790°C±3°C. Then add 20g of expanded perlite particles, namely W V =20g, and stir with an iron stirring blade with a purity of 99.8%, until the perlite particles and liquid Mg undergo a reduction reaction and disappear completely. The composition of the perlite in terms of stable oxides is: SiO 2 72.5wt%, Al 2 o 3 13.5wt%, K 2 O is 4.25wt%, Na 2 O is 3.75wt%, CaO is 0.1wt%, Fe 2 o 3 It is 0.9wt%, MgO is 0.075wt%, H or O and other non-displaying substances are analyzed to be 4.925wt%, and the sum of the compositions of various component analytes constitutes 100%.

Abstract

The invention relates to an ultra-high magnesium aluminum alloy which can make an injection body deflected and a preparation method thereof, in particular to the ultra-high magnesium aluminum alloy which is prepared by adding 13 weight percent of Mg in aluminum, adding expanded perlite to synthesize Mg2Si in situ, and adding rare earth Nd in Nd-Fe intermediate alloy mode. The ultra-high magnesium aluminum alloy can be used in externally hung type light tanks, troop vehicles and other light armors or composite armors thereof, and armor protective materials of a civil armored van, a bullet-proof car and the like. Furthermore, the invention lays foundation for the attempt to research and develop structure-function integrated light armored materials.

Description

Technical field: [0001] The invention relates to a method for preparing an ultra-high magnesium aluminum alloy capable of deflecting the injection body, in particular to a method for in-situ synthesis of Mg by adding 13wt% Mg to aluminum and adding expanded perlite 2 Si, adding rare earth Nd in the form of Nd-Fe master alloy to prepare an ultra-high magnesium aluminum alloy that can make the injection body deviate from the injection direction. Background technique: [0002] For aluminum-based alloys containing magnesium as the main alloying element, the so-called "aluminum-magnesium alloys" in the industry, they are customarily divided into two categories. One is that the aluminum-magnesium alloy with more than 2wt% magnesium added is called high-magnesium aluminum alloy; 3-5wt% aluminum-magnesium alloys such as US grades 5182, 5083, 5454, etc. The aluminum-magnesium alloys with more than 6wt% magnesium added are called ultra-high magnesium aluminum alloys. Such as German...
