Description
Technical field
The present invention relates to magnesium alloy technology, specially a kind of high-strength thin-walled part magnesium alloy and preparation method thereof.
Background technology
After the alloying such as magnesium and some metallic element aluminium, zinc, manganese, rare earth, zirconium, silver, the conjunction of the high-strength light for obtaining
Gold can be used as structural material, and these alloying elements mainly improve the performance of material by solution strengthening and precipitation strength.
Magnesium-aluminum alloys are most, the most widely used magnesium alloy series of the current trade mark.Compared with wrought magnesium alloy, magnesium is cast
Alloyapplication is particularly extensive, particularly die casting, accounts for more than 70-80%, and wherein AZ91 Alloyapplications are the most extensive, due to it
Excellent mobility, can be with the thin wall component of die casting labyrinth.The solid solubility of aluminium is 2 mass.% at room temperature, at 437 DEG C
When rise to 12.7 mass.%.Aluminium content is more than 2 mass.%, and β can be formed near as-cast magnesium alloy crystal boundary（Mg17Al12）.With
The increase of aluminium content, β phases form network in grain boundaries, but aluminium content is more than 10 mass.%, the ductility and mechanics of magnesium alloy
Performance drastically declines, and influences the yield rate of thin wall component.
The content of the invention
The present invention is carried to solve the problems, such as there is the poor influence yield rate of intensity when AZ91 magnesium alloys make thin wall component
For a kind of high-strength thin-walled part magnesium alloy and preparation method thereof.
The present invention adopts the following technical scheme that realization：High-strength thin-walled part magnesium alloy, is by following quality hundred
Divide the raw material composition of ratio：Aluminium 9-11%, zinc 0.3-0.9%, manganese 0.15-0.50%, balance of magnesium and impurity.
Aluminium, zinc, the content of manganese and ratio each other are chosen, and are drawn by substantial amounts of repetition test, aluminium content
Selection improve alloy strength and hardness, can also widen solidification zone, increase the mobility of alloy, improve casting character；Zinc contains
The selection of amount is combined with aluminium can improve the room temperature strength of alloy, with solution strengthening and ageing strengthening double action, while can subtract
The light corrosiveness for existing and causing by iron, nickel；The selection of manganese content can somewhat improve yield strength, and by except de-iron and its
His heavy metal element avoids the harmful intergranular compound of generation to improve the anti-seawater corrosion ability of magnadure, in fusion process
The harmful intermetallic compound in middle part can be separated, while crystal grain thinning, improves solderability, overcome AZ91 magnesium alloy systems
Make the presence of intensity poor influence yield rate during thin wall component.
The preparation method of high-strength thin-walled part magnesium alloy, using following steps：A, by magnesium ingot in iron ware melt
Melt, b, be subsequently heated to 650-750 DEG C, aluminium, zinc, manganese Metal are sequentially added at this temperature；C, by magnesium alloy fused mass control exist
700-750 DEG C, stood after being stirred with argon gas；D, magnesium alloy fused mass temperature is finally down to 670-690 DEG C, carries out magnesium alloy ingot
Casting.
The present invention effectively increases its performance by the improvement to magnesium alloy formula, and tensile strength has reached 280-
290MPa, yield strength has reached 180-190MPa, and mobile performance is also obviously improved, it is ensured that higher is cast into
This rate, has the advantages that process is simple, easy to operate and low cost.
