Background technique
For zinc-containing alloy because smelting technology is simple, mechanical performance, casting character, processing performance are excellent, and wearability is prominent etc.
Advantage, therefore it is referred to as " magic alloy ", become increasingly extensive inexpensive, energy saving, good of domestic and international application in recent decades
New material.
Alloy can be made with a variety of non-ferrous metals in zinc, wherein the brass of the most importantly compositions such as zinc and copper, tin, lead, also
It can be with the composition diecasting alloys such as aluminium, magnesium, copper.Zinc is mainly used for steel, metallurgy, machinery, electrical, chemical industry, light industry, military affairs and medicine
Equal fields.
The development of kirsite first has to the invention for being attributed to late nineteenth century die casting machine.Earliest reversed brass ingredient
Are as follows: Zn-6%Sn-3%Cu-0.5%A1 is mainly used to replace part Sn base product.Its main feature is that: intensity is low, and property is crisp, but ruler
Very little stability is good.Research discovery later improves aluminium content, and the various aspects of performance of alloy all improves very much, and allumen series is met the tendency of
And it gives birth to.Going deep into the development of economy with research, zinc die casting alloys produces a series of product grades, until the '20s,
The development of zinc-aluminium diecasting alloys has had reached the period of full bloom of zinc die casting alloys, the also all standardization of zinc-aluminium diecasting alloys.
With the continuous improvement of China's scientific and technological level, China is also more and more deep to the research of allumen.Although
In this way, there are also a certain distance, China compared with external some developed countries for China's allumen research level and the quality of production
Zinc-containing alloy research have got long long way to go.
Currently, main problem existing for zinc die casting alloys is that hardness is low and obdurability is poor, it is difficult to meet industrial requirement.For
This, zinc die casting alloys there are aiming at the problem that, invented and a kind of prepared high rigidity and high tough zinc die casting alloys.
Summary of the invention
The present invention uses the semisolid Zn- of Al-12.6Si intermediate alloy and near liquidus temperature with tiny Eutectic Silicon in Al-Si Cast Alloys
3Ti intermediate alloy and zinc-aluminium copper magnesium mother alloy melt carry out uniform mixed processing, prepare the pressure of a kind of high rigidity and high tenacity
Cast zinc alloy.
The zinc die casting alloys of a kind of high rigidity and high tenacity only exists Eutectic Silicon in Al-Si Cast Alloys the preparation method comprises the following steps: being added into zinc liquid
Al-12.6Si intermediate alloy or Al-12.6Si intermediate alloy and Zn-3Ti semi-solid melt is added, mixed.
Specific preparation method is:

It refines, melting Zn-xAl-yCu-zMg alloy at a temperature of 600~700 DEG C, at the same time the melting Zn- in another graphite crucible
3Ti intermediate alloy, smelting temperature control 10-80 DEG C below aluminium alloy phase line, i.e., 480-550 DEG C, add into kirsite melt
Enter Zn-3Ti semi-solid melt and solid-state Al-12.6Si intermediate alloy, uniformly mixed, alloy melt is poured into room temperature gold
Belong in casting mold, is prepared into the conjunction of Zn-11wt.%Al-1.0wt.%Cu-0.05wt.%Mg-mwt.%Si-nwt.%Ti die case zinc
Gold, it is 0.1~0.5 that wherein m, which is 0.5~1.1, n,.
Further preferably, the m is 0.8.
Purpose using solid-state Al-12.6Si intermediate alloy is to obtain tiny Eutectic Silicon in Al-Si Cast Alloys, In as far as possible in alloy structure
Under the premise of not reducing alloy ductility, the intensity and hardness of alloy are improved.
It is to make Zn using the purpose that semisolid Zn-3Ti intermediate alloy melt mode is added15Ti compound dissolves as early as possible, with
Just TiAl is formed3Phase, not molten Zn15Ti particle and TiAl3Phase plays heterogeneous forming core, thus the grain structure of refining alloy；
Smelting time can be shortened simultaneously, reduce the dissolution of Eutectic Silicon in Al-Si Cast Alloys, make in alloy structure that there are more tiny Eutectic Silicon in Al-Si Cast Alloys particles, into one
Step improves the obdurability of alloy.
The technical effect that the present invention obtains:
When reinforced phase is added to the lower Zn-11Al-1Cu-0.05Mg zinc die casting alloys of hardness, if alloy substrate is brilliant
Grain it is coarse and enhancing compare it is coarse, although the available raising of the hardness of alloy, the obdurability of alloy are lower.For example, working as
After transcocrystallized Al-Si alloy is added into alloy, although significantly improving the hardness of alloy there are more hard silicon phase in tissue,
But coarse silicon, which is met, generates the effect of isolating to alloy substrate, hence it is evident that drops low-alloyed obdurability.
The present invention mainly studies using Si alloying or uses Si, Ti composite alloying, and the present invention is by 600~700 DEG C
Zn-xAl-yCu-zMg alloy melt uniformly mixed with Zn-3Ti semi-solid melt and solid-state Al-12.6Si intermediate alloy
It closes, is then poured into room temperature metal mold, prepares the Zn-11Al-1.0Cu-0.05Mg- of higher hardness and toughness
MSi-nTi zinc die casting alloys.This preparation method has following clear superiority: using solid-state Al-12.6Si eutectic aluminum-silicon to zinc
A large amount of tiny silicon phase is introduced in alloy, can significantly improve alloy rigidity；Meanwhile as the addition semisolid Zn- into zinc liquid
When 3Ti melt, the obdurability of alloy can be further increased, it is excellent to finally obtain mechanical property with refining alloy matrix grain tissue
