Application, more and more urgent to the demand of loss of weight and environmental protection especially with modern automobile industry, the high-strength light of developing low-cost
Magnesium alloy increasingly obtains the attention of every country.
In the application of existing magnesium alloy, the ratio shared by cast magnesium alloy reaches about 90%, and wherein usage amount is bigger
Commercial cast magnesium alloy include AZ91D, AM60B, AS41 and AE42 etc., these magnesium alloys are mainly used in prepares transmission housing
Body, the general parts such as frame of handwheel and instrumental panel.But the intensity of above commercial cast magnesium alloy is insufficient for load-bearing
The assembly requirement to mechanical property.This is mainly due in process of setting, the hardening constituent of the AZ series magnesium alloy of high Al content,
Mg17Al12Being netted precipitation with the form of divorsed eutectic along crystal boundary, the plasticity causing alloy is relatively low, when stress, opens too early
Split and make alloy strength the highest.Therefore, the exploitation tough cast magnesium alloy of novel high-strength is one of cast magnesium alloy exploitation focus.
Cast magnesium alloy relies primarily on alloyage process and coordinates suitable Technology for Heating Processing to produce intercrystalline strengthening, solution strengthening
With precipitation strength effect, wherein producing precipitation strength by Ageing Treatment is to improve magnesium alloy strength, thus obtains high tough casting
One of important means making magnesium alloy.In prior art, CN102534330A discloses a kind of cast Mg alloy with high strength, this conjunction
The percetage by weight of the component of gold is Gd 8～14wt%, Y 1～5wt%, Al 0.6～2wt%, and remaining is for magnesium and can not keep away
The impurity element exempted from, after solid solution and Ageing Treatment, the tensile strength of this alloy between 300～355MPa, yield strength
Between 210～255MPa, elongation percentage, between 2～8%, has higher intensity.But this alloy needs add substantial amounts of Gd,
The rare earth element costly such as Y, directly increases the cost of alloy, and adds the density of alloy, also results in and is cast as
Shape degradation.CN1752251 discloses a kind of high-strength magnesium alloy and preparation method thereof, the percentage by weight of its constituent
It is respectively as follows: Nd2.5～3.6wt%, Zr 0.35～0.8wt%, Zn content and is not more than 0.4wt%, Ca content no more than
0.5wt%, remaining is magnesium and inevitable impurity.This alloy, after solid solution and Ageing Treatment, has higher mechanical property,
Equally containing more in tensile strength 280～320MPa, yield strength 140～155MPa, elongation percentage 5～12%, and alloy
Noble element (Nd2.5～3.6wt%), indirectly improve the cost of alloy.CN102560211A discloses a kind of containing Gd's
Cast magnesium alloy and preparation method thereof, the percentage by weight of its constituent is respectively as follows: Zn 6wt%, Y 1wt%, Zr
0.6wt%, Gd 0.5～1.0wt%, surplus is magnesium and inevitable impurity.After heat treatment the tensile strength of alloy reaches
285MPa, elongation percentage is 8.7%.But this alloy needs add the rare earth element costly such as substantial amounts of Gd, Y, Zr, directly increase
Add the cost of alloy. limit the further genralrlization application of alloy.
Visible, the tough cast magnesium alloy of the non-rare earth high-strength of developing low-cost, for reducing cost of alloy, finally realize magnesium alloy
Application on the civil areas such as auto parts and components, significant.
Summary of the invention
The problem existed for above-mentioned prior art of the present invention, it is provided that a kind of high-toughness casting magnesium alloy and preparation side thereof
Method.The novel Mg-Bi-Ca-Zn alloy of the present invention, utilizes Ca element to change Mg3Bi2Phase morphology and the effect of distribution so that close
Mg in gold3Bi2Become tiny, dispersion mutually, and by the solution treatment of appropriate temperature and time and Ageing Treatment means, regulate and control
Hardening constituent in alloy, final acquisition high-toughness casting magnesium alloy, its raw material and preparation cost are cheap.
The technical scheme is that
A kind of high-toughness casting magnesium alloy, for Mg-Bi-Ca-Zn alloy, the mass percent of its component is: Bi 3～
8.0wt%；Ca 0.1～1.2wt%；Zn 0.1～2.0wt%, remaining is Mg.
