Description

The tough as-cast aluminum alloy of novel high-strength and preparation method

Technical field

The present invention relates to aluminium alloy processing and preparation fields, and in particular to a kind of tough as-cast aluminum alloy of novel high-strength and preparation Method.

Background technology

At present, with the fast development of China's automobile industry, pursue lighter, theory faster, more environmentally friendly and be increasingly becoming vapour The core strategic of garage's industry.There is an urgent need to advanced, lightweight, the vehicle key parts of high-strength tenacity for automobile autonomous innovation Material and manufacturing technology.And it is current, in China's automobile industry, most of white body is steel.Although steel have, intensity is high, The features such as impact resistance is preferable, but its density is larger, it is difficult to realize the lightweight of automobile.And aluminium alloy is as a kind of density It is low, specific strength is high, the preferable alloy of corrosion resistance, will gradually replace part steel stamping parts, become lightweight development it is important Component.Steel are replaced using aluminium alloy, can at most make integral body loss of weight nearly 50%.So aluminium alloy structure The production and research and development of part and its material, the research and development of especially large complicated aluminum alloy junction component and its material are most important, relation To passenger car lightweight development process, technological innovation and light-weighted success or failure, there is important realistic meaning.Part research and development early period The large complicated aluminum alloy junction component that can be applied to passenger car is mostly die casting, and general die casting can not be heat-treated, therefore intensity It is relatively low, plasticity is poor, the requirement of the plasticity and security needed for body structural member can not be met.Other casting methods such as vacuum Die casting, low pressure casting part and tilted casting part, although these types of method can be heat-treated, follow-up heat treatment process is more Complexity, and under high temperature heat-treatable aluminum alloy deformation it is serious, subsequently also need to be corrected aluminum alloy junction component after heat treatment, It can further increase to energy consumption, frock, man-hour, artificial requirement, extend the manufacturing cycle, increase manufacturing cost.Based on Upper reason, current automobile manufacturing industries are badly in need of a kind of new tough as-cast aluminum alloy of height without subsequent heat treatment.Nanometer TiB2、NbB2, TiC ceramic particles there is high-melting-point, high rigidity, good corrosion resistance and very high electrical conductivity, and Size is small, and quantity is more, is all significantly improved by ceramics particle strengthened aluminum alloy materials its intensity, plasticity.Relatively low pottery Porcelain granule content can obtain strengthens effect well, and, but also preparation process is easy, cost is easily controllable for this.By nanometer The as-cast aluminum alloy that grain is strengthened is used directly for the preparation of structural member, and any subsequent heat treatment technique is not required, significantly simplifies The production technology of aluminium alloy.Technical solution of the present invention be designed by al alloy component, melting, refining, then add in Nano-ceramic particle reinforced aluminium alloy, while the content of Fe, Ti, Zn impurity element is strictly controlled, it prepares a kind of new without heat The tough as-cast aluminum alloy of height of processing.The intensity and plasticity of aluminium alloy prepared by the preparation method being related to by this patent have larger The raising of degree, this programme can be to avoid large aluminum alloy component heat treatment process, a large amount of schools after saving heat treatment and heat treatment Just required frock, man-hour, manually, while reduce energy energy consumption, for simplify alloy production technique, reduce cost have it is important Application value.

The content of the invention

Problem to be solved by this invention is to provide a kind of tough as-cast aluminum alloy of novel high-strength and preparation method.

The purpose of the present invention can be achieved through the following technical solutions：

A kind of tough as-cast aluminum alloy of novel high-strength and preparation method, comprise the following steps：

(1) Step 1: aluminium alloy matches somebody with somebody when melting：

With fine aluminium, Al-Si12Intermediate alloy, pure magnesium, fine copper are material preparation.

It is according to the ingredient of aluminium alloy：Si：9.30wt.%~10.5wt.%；Mg：0.39wt.%~2.70wt.%； Cu：0.00wt.%~1.00wt.%；Zn：≤ 0.15wt.%；Ti：≤ 0.10wt.%；Fe：≤ 0.10wt.%；Surplus is Al prepares aluminium alloy.The raw material for preparing aluminium alloy is added to together in dry smelting furnace, is heated to temperature as 1003- Melting 0.5h~1h under the conditions of 1023K, obtains molten aluminium alloy；

(2) Step 2: alloy refining：

Smelting molten aluminum goes to holding furnace heat preservation, then carries out furnace refining, under the conditions of temperature is 1003-1023K, Rotation is blown to pop one's head in and stretches into heat preservation furnace bottom, chlorine is passed through to molten aluminum from rotation air blowing probe and argon gas is refined, blow 5-10min is handled, measures the liquid hydrogen content of molten aluminum during refining using online hydrogen meter.
