Description
Technical field
The invention belongs to fining agent technical field, a kind of aluminium zirconium carbon rare earth fining agent and preparation method thereof is specifically related to.
Background technology
Magnesium alloy is most light structural metallic materials in current commercial Application, with density is small, specific strength and specific stiffness it is high,
The advantages of damping shock absorption is good, effectiveness is good, in automobile, motorcycle, electronic information, track traffic, Aero-Space etc.
Field has very big application potential.But the absolute intensity of most of magnesium alloys is still relatively low, secondly, magnesium alloy is close-packed hexagonal
Crystal structure, its temperature-room type plasticity deformability is poor, limits the products such as wrought magnesium alloy strip, tubing, section bar and forging
Production and application.Crystal grain refinement is the effective ways for improving magnesium alloy mechanical property and improving magnesium alloy plastic deformation ability, together
When crystal grain refinement also contribute to the uniformity of Magnesium Alloy, improve the decay resistance of magnesium alloy, reduce hot tearing and group
Knit the casting flaw such as loose.
Early in 1931, people found that element Zr has obvious grain refining effect to pure magnesium, were added in pure magnesium liquid
Minimal amount of zirconium, so that it may greatly improve the nucleation rate of pure magnesium, plays the effect of crystal grain thinning.But the elements such as Zr and Al, Mn can shape
Into the compound of stabilization, the effect of crystal grain thinning is not had.For example, adding Zr, Zr and the Al to be formed in the magnesium alloy containing Al
The Al of stabilization3Zr compounds, and Al3The B.C.T. shape crystal structure of Zr is entirely different with the Patterns for Close-Packed Hexagonal Crystal structure of magnesium, and
The lattice parameter of the two differs greatly, therefore, Al3Zr cannot function as the heterogeneous forming core core of magnesium crystal grain, while forming Al3Zr will
Cause the loss of Al and Zr in magnesium alloy.Therefore, single Zr elements cannot function as containing Al, Mn element magnesium alloy crystal grain it is thin
Agent.Later it is found that the characteristics of ZrC particles have fusing point high, good stability, particularly ZrC particles are all solid matter six with magnesium
The square crystal structure and lattice parameter of the two is close, lattice constant mismatch degree is very low, according to metallography lattice match principle,
ZrC particles are the excellent heterogeneous nucleis of magnesium, and the aluminium zirten containing ZrC particles is developed accordingly as magnesium alloy
Grain refiner, solve the problems, such as the crystal grain refinement of the magnesium alloy containing elements such as Al, Mn.
At present, aluminium zirten is mainly prepared using thermit reaction method, i.e., with zirconium source and carbon source as raw material, by zirconium source and carbon
Source is added in aluminum melt, by reacting aluminium alloy of the generation containing ZrC particles, aluminium alloy then is cast as into aluminium zirconium carbon again and is closed
Ingot or continuous casting and rolling are into aluminium zirten bar.But in the preparation method, due to ZrC particles large number of in aluminium alloy and
Size is tiny, has very strong compatibility between particle, along with there is nonequilibrium freezing characteristic in aluminium alloy process of setting, most
Cause there is serious ZrC particle segregations reunion in aluminium zirten eventually, and the segregation of ZrC particles reunion can not only reduce crystal grain
The grain refining capability of fining agent, accelerates the decline of grain refining capability, and is produced from the surface for also resulting in magnesium alloy deep processed product
The defects such as greensand eye, pin hole.In addition, the method can produce substantial amounts of hydrogen and oxidation because temperature is high and thermit reaction violent
The slags such as aluminium, not only result in serious environmental pollution, can also increase the nonmetal inclusion such as hydrogen, aluminum oxide in aluminium zirten
The content of the metallic impurity elements such as thing and Fe, Si, reduces the cleanliness factor of grain refiner, and finally influences whether to use crystal grain
The cleanliness factor of the magnesium alloy of fining agent, it is impossible to meet high-cleanness, the production need of bright, high-accuracy magnesium alloy deep processed product high
Will.
The content of the invention
Above-mentioned there is problem and shortage it is an object of the invention to be directed to, there is provided a kind of ZrC particles are evenly distributed, crystal grain is thin

Rare earth is surface active element, can reduce the surface tension of aluminium zirten liquid, improves the mobility of aluminium zirten liquid, drop
The surface energy of low ZrC particles, the tendency so that segregation for reducing ZrC particles is reunited, makes ZrC particles be more evenly distributed in aluminium zirconium
In carbon alloy, increase effective number of nuclei of ZrC particles, and then improve the grain refining capability of aluminium zirten.In addition, ZrC
Particle distribution is more uniform, can just slow down sinking speed of the ZrC particles in liquid magnesium alloy, so as to improve the anti-of aluminium zirten
Fading of refinement ability.（2）Secondly, rare earth element has chemism very high, with the metal such as hydrogen, oxygen, iron, silicon and nonmetallic miscellaneous
Prime element has very strong chemical affinity, can be with the rare earth chemical combination of the impurity such as hydrogen, oxygen, iron, silicon reaction generation high stability
Thing, and eventually through floating or sinking to being removed, so as to the catharsis to aluminium zirten liquid with depth, make aluminium zirconium
Carbon alloy obtains cleanliness factor higher, meets high-cleanness, the production needs of bright, high-accuracy magnesium alloy deep processed product high,
With wide market application foreground.
The lot of experiments of inventor shows, addition containing tetra- kinds of LREEs of Pr, Nd, Pm, Sm and Tb, Dy, Ho,
Six kinds of effects of the mischmetal of heavy rare earth element of Tm, Yb, Lu are all better than adding a kind of or a few rare earth element effect.
It also requires it is realized that, expensive due to rare earth element, excessive addition rare earth element can also increase aluminium zirten
Production cost.Through considering effect and cost factor, the addition of Re mischmetals is selected 0.1~0.5%.
