Abstract
A high-strength AlSi alloy is prepared from Si, Mg, Ti, Re mixture and Al through conventional smelting. Its advantages are high strength increased by 35%, low cost, and good performance and lustre.
Description
Technical field: the present invention is a kind of high-strength aluminium silicon alloy and production method thereof, belongs to the technical field of non-ferrous metal.
Technical background: aluminum silicon alloy has good processing properties, as structured material, because aluminum silicon alloy light specific gravity, specific tenacity and than stiffness height, its application prospect is very good, be widely used in automotive industry, be used for engine body material, steam cylinder piston material etc., the aluminum silicon alloy intensity that traditional technology is produced is on the low side, unit elongation is low, and it is limited in industrial applicability.Sometimes, in order to obtain the aluminium alloy of high strength, high-elongation, have in aluminum silicon alloy, add copper and other expensive metal, thereby increased the production cost of this aluminum silicon alloy, even like this, the use of this metalloid material still is subjected to the restriction of price, can not be extensive use of.
Summary of the invention: the objective of the invention is to: a kind of high-strength aluminium silicon alloy and production method thereof are provided; This method is to add some rare earth elements in process of production, utilizes the characteristics of rare earth element self, improves the performance of aluminum silicon alloy, and the product price that obtains is cheap, intensity is high, performance is good, can widespread use; The present invention constitutes like this: the high-strength aluminium silicon alloy, and calculates according to composition by weight: it is by Si 0-13%, Mg 0-11%, Ti 0-0.35%, mishmetal 0.01-0.08%, all the other are the Al formation; Described mishmetal is the composition of any one rare earth element or two kinds or above rare earth element, and specifically: described mishmetal is the composition a kind of or element more than two kinds and two kinds among niobium, cerium, lanthanum, four kinds of rare earth elements of Yttrium.The production method of this high-strength aluminium silicon alloy is: according to given composition by weight, adopt the method for conventional melting to carry out melting mishmetal and aluminum base alloy and other alloy raw materials and obtain this product, contain Si 0-13% in the product, Mg 0-11%, Ti 0-0.35%, mishmetal 0.01-0.08%, all the other are Al; Specifically: according to given composition by weight, adopt the method for conventional melting to carry out melting the composition a kind of or element more than two kinds and two kinds among niobium, cerium, lanthanum, four kinds of rare earth elements of Yttrium and aluminum base alloy and other alloy raw materials and obtain this product, contain Si 0-13% in the product, Mg 0-11%, Ti 0-0.35%, the composition 0.01-0.08% a kind of or element more than two kinds and two kinds among niobium, cerium, lanthanum, four kinds of rare earth elements of Yttrium, all the other are Al.
Compared with prior art: product provided by the invention is under the processing condition that do not change the basic alloy production of original aluminium (silicon), by adding trace rare-earth element, the basic alloy novel material of the aluminium that contains trace rare-earth element (silicon) that makes increases 35% than aluminium (silicon) the base alloy material intensity σ b of former composition, and do not increase its production cost, the production method that is provided does not change traditional production method, do not increase production cost, the product cost that makes is low, intensity is high, performance, good, the applied range of color and luster.
Rare earth metal has vital role and extensive use in contemporary information, biology, novel material, new forms of energy, space science technology and ocean exploitation research; Rare earth is good scavenging agent and the alterants of non-ferrous metal such as aluminium, magnesium, zinc, copper; The electron structure of rare earth element is special, internal layer 4f track unpaired electron is many, nonmagnetic atom is apart from height, electronic level and spectral line are abundant, rare earth metal is active, lose the compound that electronics forms multiple valence state, polygamy figure place easily, rare earth metal easily and the oxygen in non-ferrous metal and the alloy thereof, sulphur, nitrogen, gaseous impurities effects such as carbon generate stable compound, thereby played the effect of purification and impurity removal matter, general as long as add some thousandths of, just can play detrimental impurity influence, crystal grain thinning and the effect that produces alloying eliminated.
The rare earth metal additive can form intermetallic compound or alloy phase with the matrix metal of non-ferrous metal alloy and the performance of metallic substance is greatly improved, improve the processing and the use properties of material, use rare earth and can improve product strength and produce different color and lusters, expand its range of application greatly with the aluminium alloy reaction.
